How a Bodhisattva Proves He Means It
Shansheng puts the question as plainly as it can be put: how does a bodhisattva know, of himself, whether he is a bodhisattva in name only or a bodhisattva true in meaning? The Buddha's answer is not a definition but a catalogue — his own past lives, one after another, in which body and life were given up without the mind once turning back: austerities that outdid the ascetics who invented them, a body carved into thirty-six hundred lamps, a life handed over for a single dove, animal bodies inhabited without ever being mastered by them, a fish's flesh and a medicine tree's bark offered to the starving and the sick. Only at the end does the chapter turn the test back on the listener, and conclude — against easy assumption — that this resolve is harder, not easier, for the person still living at home.
1. Milestone: Shansheng's Question — What Makes a Bodhisattva "True in Meaning"?
The chapter opens with a single, direct question from Shansheng: is there any way a bodhisattva can actually verify, for himself, that he deserves the name — rather than simply assuming it?
善生言：「世尊！義菩薩者，云何自知是義菩薩？」
Shansheng said: "World-Honored One, as for a bodhisattva true in meaning — how does he know, of himself, that he is a bodhisattva true in meaning?"
Taixu points out that only the Buddha himself can see with full clarity which practitioners are bodhisattvas in name only and which are true in meaning — an ordinary practitioner has no such vantage point on his own attainment. That is exactly why the question matters: anyone actually walking the bodhisattva path needs some way to check himself honestly, rather than simply trusting the label he has been given. Shansheng asks on behalf of every such practitioner, and the whole of the chapter that follows is the Buddha's answer.
2. Milestone: A Lifetime of Austerity, and Four Reasons to Give Up the Body
The Buddha answers by recalling his own past lives. He begins with a stretch of ascetic practice so extreme it outdid the non-Buddhist ascetics who originated it, then names, plainly, the four reasons any bodhisattva might actually give up body and life.
「善男子！菩薩摩訶薩修苦行時，先自誡心。善男子！我念往昔行菩薩道時，先從外道受苦行法，至心奉行，心無退轉。無量世中以灰塗身，唯食胡麻、小豆、粳米、粟米等，日各一粒；荊棘、惡刺、㭬木、地石以為臥具；牛屎、牛尿以為病藥。盛夏之月，五熱炙身；孟冬之節，凍氷儭體。或受草食、根食、莖食、葉食、果食、土食、風食，作如是等諸苦行時，自身他身俱無利益。雖爾，猶故心無退轉，出勝一切外道苦行。」
"Good son, when a bodhisattva-mahāsattva undertakes ascetic practice, he first admonishes his own mind. Good son, I recall that in ages past, when I practiced the bodhisattva path, I first took up the ascetic disciplines of the non-Buddhist paths, carrying them out with utmost sincerity, my mind never turning back. Through countless lifetimes I smeared my body with ashes, eating only sesame, small beans, unhusked rice, or millet — a single grain of each per day; I took brambles, thorns, dead wood, and bare stone and rock as my bedding; I took cattle dung and cattle urine as my medicine when ill. In the height of summer I let the five fires scorch my body; in the depth of winter I let the freezing ice press against my flesh. At times I lived on grass alone, or on roots, on stalks, on leaves, on fruit, on earth, or on wind alone. Undertaking austerities of this kind brought no real benefit to myself or to others. And yet my mind never once turned back, and I surpassed every austerity ever practiced by the non-Buddhist paths."
「善男子！我於往昔為四事故，捨棄身命：一者、為破眾生諸煩惱故，二者、為令眾生受安樂故，三者、為自除壞貪著身故，四者、為報父母生養恩故。菩薩若能不惜身命，即自定知是義菩薩。」
"Good son, in ages past I gave up my body and my life for four reasons: first, to break the afflictions of sentient beings; second, to bring sentient beings ease and happiness; third, to destroy in myself the craving attachment to this body; and fourth, to repay my parents for the kindness of bearing and raising me. If a bodhisattva is able to hold his body and life this lightly, he may know for certain, of himself, that he is a bodhisattva true in meaning."
Taixu reads "first admonishes his own mind" as a kind of self-briefing rather than mere resolve-building: before matching the ascetics' own extremes, the bodhisattva reminds himself exactly why he is about to do so. Ascetic practice already commanded real respect among ordinary people of the time — it was, in effect, the non-Buddhist teachers' proof of sincerity — so a bodhisattva hoping eventually to turn those same people toward the true Dharma first had to be seen matching or surpassing that same standard, outdoing every one of their disciplines in turn, even though, as the text itself concedes, none of it brought genuine benefit to anyone by itself. He glosses a few of the harder terms in passing — the "dead wood" used as bedding is exactly that, wood already dead rather than a living branch, and living on nothing but earth or on wind alone were themselves standard non-Buddhist austerities of the era, not invented details.
His summary of the whole passage is a single, plain equivalence: whoever can actually give up body and life, for the Dharma and for other beings, has by that very act already met the definition of a bodhisattva true in meaning — nothing further needs to be proven.
3. Milestone: Carved Into Lamps, Wounded a Thousand Times, Given for a Dove
Three specific past-life sacrifices follow, each ending in the same refrain: the affliction was still fully present, the pain was genuinely felt, and still the mind did not turn back.
「善男子！我於往昔為正法故，剜身為燈三千六百。我於爾時具足煩惱，身實覺痛，為諸眾生得度脫故，諭心令堅，不生退轉。爾時即得具足三事——一者、畢竟無有退轉，二者、得為實義菩薩，三者、名為不可思議——是名菩薩不可思議。」
"Good son, in ages past, for the sake of the true Dharma, I carved my own body into three thousand six hundred lamps. At that time I still possessed the afflictions in full, and my body genuinely felt the pain — yet for the sake of bringing sentient beings to liberation, I steadied my mind and made it firm, and no retreat arose in it. At that time I thereby fully possessed three things: first, ultimate freedom from any turning back; second, the attainment of being a bodhisattva true in meaning; and third, being called inconceivable. This is called the bodhisattva's inconceivable quality."
「又我往昔為正法故，於一劫中，周身左右受千瘡苦。爾時具足一切煩惱，身實覺苦，為諸眾生得度脫故，諭心令堅，不生退轉，是名菩薩不可思議。」
"Again, in ages past, for the sake of the true Dharma, throughout an entire kalpa I bore the suffering of a thousand wounds covering my whole body, left and right. At that time I still possessed every affliction in full, and my body genuinely felt the suffering — yet for the sake of bringing sentient beings to liberation, I steadied my mind and made it firm, and no retreat arose in it. This too is called the bodhisattva's inconceivable quality."
「又我往昔為一鴿故，棄捨是身。爾時具足一切煩惱，身實覺苦，為諸眾生得度脫故，諭心令堅，不生退轉，是名菩薩不可思議。」
"Again, in ages past, for the sake of a single dove, I gave up this very body. At that time I still possessed every affliction in full, and my body genuinely felt the suffering — yet for the sake of bringing sentient beings to liberation, I steadied my mind and made it firm, and no retreat arose in it. This too is called the bodhisattva's inconceivable quality."
Taixu underlines "百孔千瘡" — a hundred holes, a thousand wounds — as an idiom pushed to its most literal, physical extreme precisely to make a point about degree: this is not gentle self-denial but suffering carried as far as suffering can go, and it is only against that extremity that "the mind did not turn back" actually means something. He also stresses a detail easy to read past: in every one of these three episodes, the text insists the afflictions were still fully present and the pain genuinely felt. Nothing here is a painless illusion performed for effect — the bodhisattva is not spared the suffering; he simply refuses to let it turn his mind back.
4. Milestone: Turning Bad Companions and Afflictions into Allies
A striking reversal follows: what an ordinary being treats as an enemy — affliction itself, and the bad company that comes with it — the bodhisattva instead treats as an ally accompanying him along the path, even to the point of deliberately taking on an animal's body to tame beings no other teaching could reach.
「善男子！一切惡友、諸煩惱業，即是菩薩道莊嚴伴。何以故？一切凡夫無有智慧、正念之心，故以煩惱而為怨敵，菩薩智慧、正念具足，故以煩惱而為道伴；惡友及業，亦復如是。善男子！捨離煩惱，終不得受惡有之身。是故菩薩雖現惡業，實非身、口、意惡所作，是誓願力。以是願力受惡獸身，為欲調伏彼畜生故。菩薩現受畜生身已，善知人語、法語、實語、不麁惡語、不無義語，心常憐愍，修集慈悲，無有放逸，是名菩薩不可思議。」
"Good son, every evil companion and every action born of affliction is itself an adornment accompanying the bodhisattva's path. Why is this? Every ordinary being, lacking wisdom and lacking a mind of right mindfulness, takes affliction as an enemy; the bodhisattva, fully possessed of wisdom and right mindfulness, takes affliction instead as a companion on the path — and it is exactly the same with evil companions and their karma. Good son, one who has genuinely abandoned affliction will never again take on a body born of evil existence. This is why, even when a bodhisattva manifests what looks like evil action, it is in truth not something done by an evil body, speech, or mind — it is the power of his own vow. It is by the power of that very vow that he takes on the body of a fierce beast, precisely in order to tame and subdue those animals themselves. Once the bodhisattva has taken on an animal's body, he still understands human speech, the speech of the Dharma, and truthful speech; he uses no coarse or vicious speech, no speech without meaning; his mind remains constantly compassionate, he continues to cultivate loving-kindness and compassion, and he is never negligent. This is called the bodhisattva's inconceivable quality."
Taixu draws out a correlation here that runs through the whole passage: the higher a bodhisattva's actual realization, the lower — in outward appearance — his conduct may need to go. A bodhisattva of lesser attainment, he notes, can only save beings among humans and gods; it takes a bodhisattva of the very highest attainment, of the stature of Avalokiteśvara or Kṣitigarbha, to actually enter the three evil destinies and work to save beings there directly. Treating affliction and bad company as companions on the path, rather than as enemies to be kept at a safe distance, is precisely what makes it possible for a bodhisattva to work even among rākṣasas and hungry ghosts, in the most degenerate corners of the world, without being degraded by the contact himself.
5. Milestone: Born Bear, Ox, Serpent, Dragon — Mindfulness Beyond Species
The catalogue of past lives widens into a long list of animal bodies. In every one of them, the same claim is repeated: the afflictions were present exactly as they always are, yet had no power to actually master him.
「善男子！我於往昔受熊身時，雖具煩惱，煩惱於我無自在力。何以故？具正念故，我於爾時，憐愍眾生，擁護正法，修行法行。受瞿陀身、劫賓耆羅身、兔身、蛇身、龍身、象身、金翅鳥身、鴿身、鹿身、獼猴、羖羊、雞雉、孔雀、鸚鵡、蝦蟇——我受如是鳥獸身時，雖具煩惱，煩惱於我無自在力。何以故？具正念故，憐愍眾生，擁護正法，修行法行。」
"Good son, when in ages past I took on the body of a bear, though I still possessed the afflictions in full, the afflictions had no power to master me. Why was this? Because I possessed right mindfulness — at that time I still felt compassion for sentient beings, still upheld and protected the true Dharma, and still carried out the practice of the Dharma. So too when I took on the body of an ox, of a kapiñjala bird, of a hare, a snake, a dragon, an elephant, a garuḍa, a dove, a deer, a monkey, a ewe, a cock or pheasant, a peacock, a parrot, or a toad — whenever I took on such a bird's or beast's body, though I still possessed the afflictions in full, the afflictions had no power to master me. Why was this? Because I possessed right mindfulness, felt compassion for sentient beings, upheld and protected the true Dharma, and carried out the practice of the Dharma."
Taixu cross-references another scripture's account of this same bear-body jātaka, in which the bear actually raised and protected a human child, to make concrete what "the afflictions have no power over me" is really claiming: the affliction has not vanished, and never does — it is simply no longer in the driver's seat. He glosses a few of the less familiar names in passing, for readers unfamiliar with them — the ox-body, the ewe, the kapiñjala as a kind of bird — but reads the entire list as making one sustained point rather than sixteen separate anecdotes: it is right mindfulness itself, not any particular species or set of circumstances, that actually determines whether affliction masters a being or is instead mastered by it.
6. Milestone: The Great Fish and the Medicine Tree
The jātaka catalogue closes with two vows made specifically to match a crisis: a body of food during famine, a body of medicine during plague — each one a form freely taken up because it was exactly what suffering beings needed at that moment.
「善男子！於飢饉世，我立大願，以願力故受大魚身，為諸眾生離於飢渴，食我身者，修道、念道，無惡罪過；疾疫世時，復立大願，以願力故身為藥樹，諸有病者，見、聞、觸我，及食皮膚、血肉、骨髓，病悉除愈。善男子！菩薩摩訶薩受如是苦，心不退轉，是名義菩薩。」
"Good son, in an age of famine I set a great vow, and by the power of that vow took on the body of a great fish, so that sentient beings might be freed from hunger and thirst; those who ate of my body took up the path and kept the path in mind, and committed no evil transgression. In an age of plague I likewise set a great vow, and by the power of that vow became a medicine tree; all who were sick, upon seeing me, hearing of me, touching me, or eating my bark, flesh, blood, or marrow, were entirely cured of their illness. Good son, when a bodhisattva-mahāsattva undergoes suffering of this kind and his mind does not turn back, this is called a bodhisattva true in meaning."
These two vows complete the jātaka sequence Taixu treats as a single unit (his section heading calls it simply "enumerating past-life conduct"): austerities, self-mutilation, the dove, sixteen animal bodies, and now a fish and a tree, each body freely chosen to match exactly what a given crisis required. The pattern across the entire list is the same one Taixu names for the bear: not the absence of affliction or of physical suffering, but a vow strong enough that neither one ever turns the mind back — whether the body wearing that vow is a starving ascetic, a wounded man, a dove's rescuer, a bear, or, here, dinner and medicine for beings who have nothing else.
7. Milestone: Six Perfections Without Seeking Their Fruit
Having finished with his own specific past lives, the Buddha turns to bodhisattva conduct in general — a set of principles any practitioner can measure himself against, regardless of which body or circumstance he currently occupies.
「菩薩修行六波羅蜜時，終不悕求六波羅蜜果，但以利益眾生為事。菩薩深知生死過患，所以樂處，為利眾生受安樂故。菩薩了知解脫安樂、生死過患而能處之，是名菩薩不可思議。菩薩所行，不求恩報；受恩之處，常思反報。善男子！一切眾生常求自利，菩薩所行恒求利他，是名菩薩不可思議。菩薩摩訶薩具足煩惱，於怨親所平等利益，是名菩薩不可思議。」
"When a bodhisattva practices the six perfections, he never hopes to gain their fruit for himself; he makes only the benefiting of sentient beings his concern. The bodhisattva fully knows the faults and dangers of birth-and-death, and yet is glad to dwell within it, precisely so that he may bring benefit and ease to sentient beings. That the bodhisattva fully understands both the ease of liberation and the dangers of birth-and-death, and is nonetheless able to dwell in the latter, is called the bodhisattva's inconceivable quality. In whatever the bodhisattva does, he seeks no repayment for his own kindness; yet wherever he himself has received a kindness, he constantly thinks of how to repay it. Good son, all sentient beings constantly seek their own benefit, while whatever the bodhisattva does constantly seeks the benefit of others — this is called the bodhisattva's inconceivable quality. That a bodhisattva-mahāsattva, while still possessing the afflictions in full, benefits enemy and kin alike, with no difference between them, is called the bodhisattva's inconceivable quality."
Taixu marks this passage as a deliberate structural turn in the chapter, moving from a list of the Buddha's own specific past-life examples to what he titles, simply, "broadly clarifying bodhisattva conduct" — from what one particular being did, in one particular body, to a set of tests any bodhisattva can actually check himself against in the present. Choosing to remain in birth-and-death while fully seeing its dangers, refusing to seek repayment while still remembering every kindness received, treating enemy and kin with the same regard while afflictions are still fully present in oneself — none of these require a past-life miracle to attempt; they describe an ordinary bodhisattva's ordinary conduct, examined closely enough to see what it actually demands.
8. Milestone: Gentle Speech, Tireless Teaching
The Buddha contrasts his own method of teaching directly against the non-Buddhist ascetics' harsher approach, then adds two further tests: whether generosity holds up against a demand far larger than what is offered, and whether patience with the hardest students to reach ever runs out.
「善男子！若諸外道化眾生時，或以惡語、鞭打、罵辱、擯之令出，然後調伏。菩薩不爾，化眾生時，無麁惡語、瞋語、綺語，唯有濡語、真實之語，眾生聞已，如青蓮遇月，赤蓮遇日。善男子！菩薩施時，財物雖少，見多乞求，不生厭心，是名菩薩不可思議。菩薩教化盲、聾、瘖、瘂，愚癡、邊地惡眾生時，心無疲厭，是名菩薩不可思議。」
"Good son, when the non-Buddhist paths teach and transform sentient beings, they may use harsh words, whipping, scolding and humiliation, or drive the person out and expel them, only afterward bringing them to submission. The bodhisattva is not like this. When he teaches and transforms sentient beings he uses no coarse or vicious speech, no angry speech, no idle or flattering speech — only gentle speech and truthful speech; and sentient beings, upon hearing it, respond as a blue lotus responds to the moon, or a red lotus responds to the sun. Good son, when the bodhisattva gives, even though his own wealth and goods are few, if he meets those who beg for much, no thought of weariness or aversion arises in him — this is called the bodhisattva's inconceivable quality. When the bodhisattva teaches and transforms the blind, the deaf, the mute, the foolish, or beings of coarse and remote borderlands, his mind knows no fatigue or aversion — this too is called the bodhisattva's inconceivable quality."
Taixu explains the flower imagery quite literally: a blue lotus genuinely opens at moonrise, a red lotus genuinely opens at sunrise, so the comparison is not decorative but exact — the bodhisattva's gentle, truthful speech is the one condition under which beings open, in the same automatic way a flower opens to the light suited to it. He also draws a sharp contrast with ordinary affection: an ordinary person loves what is already attractive and turns away from whatever is not, while the bodhisattva's compassion runs in the opposite direction entirely — the less appealing or more difficult a being is to reach, the more that difficulty itself draws out his care, precisely because that being needs it more, not less.
9. Milestone: Ten Inconceivable Qualities of the Bodhisattva
The chapter names ten specific "inconceivable" qualities in three short groups — four, then three, then three more — closing in on exactly what makes a bodhisattva's conduct genuinely hard to match.
「善男子！菩薩有四不可思議：一者、所愛重物能以施人，二者、具諸煩惱能忍惡事，三者、離壞之眾能令和合，四者、臨終見惡說法轉之。是名菩薩四不可思議。」
"Good son, the bodhisattva has four inconceivable qualities: first, he is able to give away to others even what he himself loves and treasures most; second, though he still possesses every affliction, he is able to bear with evil circumstance; third, he is able to bring back into harmony a following that has broken apart and scattered; and fourth, when someone is dying and sees fearful, evil visions, he is able to speak the Dharma and turn that person's mind around. These are called the bodhisattva's four inconceivable qualities."
「復有三事不可思議：一者、呵責一切煩惱，二者、處煩惱中而不捨之，三者、雖具煩惱及煩惱業而不放逸。是名菩薩三不可思議。」
"There are, further, three more inconceivable qualities: first, he rebukes every affliction in himself; second, when others are caught in the midst of affliction, he does not abandon them on that account; and third, though he himself still possesses afflictions and the karma born of them, he is never negligent. These are called the bodhisattva's three inconceivable qualities."
「復有三事不可思議：一者、始欲施時心生歡樂，二者、施時為他不求果報，三者、施已心樂不生悔恨。是名菩薩三不可思議。」
"There are, further, three more inconceivable qualities: first, at the very moment he first intends to give, joy already arises in his mind; second, while giving, he acts entirely for the sake of the other and seeks no fruit of reward for himself; and third, once the giving is done, his mind remains joyful and no regret ever arises in it. These are called the bodhisattva's three inconceivable qualities."
Taixu is careful to define what "inconceivable" actually means here, since the word carries a much stronger technical sense elsewhere in the tradition: strictly, it describes what lies utterly beyond language and conceptual thought altogether, but in this chapter it is being used more practically, for whatever an ordinary being genuinely finds difficult to accomplish. He also clarifies the pairing in the second group, which is easy to misread as directed at a single object: "rebukes... does not abandon" actually points at two different things — a bodhisattva rebukes affliction in himself, but does not abandon another person on account of that other person's affliction. And he distinguishes "affliction" from "affliction-karma" precisely: the affliction itself is a state of mind, while the karma it gives rise to plays out through body, speech, and mind alike.
Read together, Taixu treats all ten as a single continuous portrait rather than an arbitrary checklist: a mind that gives without being asked twice, that stays steady under provocation, that keeps working on itself while never giving up on anyone else, and that finds its own joy in giving before, during, and after the fact — with no gap anywhere in that sequence for regret to enter.
10. Milestone: Self-Examination, and Why the Householder's Path Is Harder
The chapter ends by turning the entire question back on the practitioner himself, then closes with a conclusion that runs against easy assumption: this resolve is harder, not easier, to sustain for someone who has not left the household life.
「善男子！菩薩摩訶薩作是行時，自觀其心：『我是名菩薩也？義菩薩乎？』眾生若能作如是事，當知是人即義菩薩也。」
"Good son, when a bodhisattva-mahāsattva carries out practice of this kind, he examines his own mind, asking: 'Am I merely called a bodhisattva in name, or am I truly a bodhisattva in meaning?' If a sentient being is able to carry out things of this kind, know that this person is indeed a bodhisattva true in meaning."
「善男子！菩薩有二種：一者、在家，二者、出家。出家菩薩作如是事，是不為難；在家菩薩為如是事，是乃為難。何以故？在家之人多惡因緣所纏繞故。」◎
"Good son, there are two kinds of bodhisattva: the householder bodhisattva and the monastic bodhisattva. For a monastic bodhisattva to carry out things of this kind is not so difficult; for a householder bodhisattva to carry out things of this kind is truly difficult. Why is this? Because a person living at home is entangled by so many evil circumstances and conditions."
Taixu reads the self-examining question as already most of its own answer: a bodhisattva who genuinely, honestly checks whether he is a bodhisattva in name only or true in meaning has, in the very act of asking, already shown himself to be the latter — a bodhisattva in name only would never think to ask in the first place. He closes by underlining why the chapter ranks the householder's path as the harder one rather than the easier: entangled daily by family, livelihood, and worldly obligation in ways a monastic simply is not, a householder bodhisattva who nonetheless manages this same conduct has accomplished something genuinely greater, not lesser.
Taixu takes this conclusion personally, closing his own lecture notes on the chapter with a direct exhortation to his audience: that everyone who has heard this sutra should actually practice what it teaches, so as not to let the Buddha's own encouragement in this chapter go to waste.
