★☆☆☆☆ — about as plain and direct as this collection gets
Why this discourse, fiftieth
The Book of the Threes opens as plainly as a teaching can: three roots, greed, hate, and delusion, and a single verse comparing the harm they do to the person who holds them to a specific, almost domestic image — a bamboo destroyed by its own fruit.
Reading guide
The teaching in one sentence
There are three unskillful roots — greed, hate, and delusion — and when they arise inside a person of wicked heart, they harm that very person, exactly as a particular kind of bamboo is destroyed by the fruit it bears.
No narrative frame, and a new book
As with almost every discourse in this collection, no place, audience, or occasion is given; the teaching opens directly with the Itivuttaka's formula. This discourse is also the first of the Book of the Threes, following immediately after the Book of the Twos closes at Iti 49 — the collection's structure shifts here from teachings built around two factors to teachings built around three, and this is the very first of fifty such discourses.
Three roots, named plainly
The prose could hardly be more direct: "Mendicants, there are these three unskillful roots. What three? Greed, hate, and delusion. These are the three unskillful roots." Akusalamūla, "unskillful root," names something more basic than any single bad action — these three are roots in the sense that unskillful deeds of body, speech, and mind are all said, elsewhere in the tradition, to grow out of them. This discourse does not argue the point or illustrate it with examples; it simply states the list.
Self-inflicted harm
The single verse supplies the discourse's only elaboration: "When greed, hate, and delusion, have arisen inside oneself, they harm a person of wicked heart, as a bamboo is destroyed by its own fruit." The image is specific — certain bamboo species are known to die once they bear fruit, their own reproductive act becoming the cause of their destruction. Applied to greed, hate, and delusion, the comparison makes a precise point: these three do not simply produce external consequences elsewhere, they consume the very person in whom they arise, using that person's own inner resources to do so.
A recurring image
The same bamboo image appears independently in the Dhammapada, applied there to wrong views rather than to the three roots directly — a sign that this was a recognized figure of speech in the early tradition for self-destruction that looks, from outside, like ordinary flourishing (a bamboo fruiting looks like success, not decline, until the plant dies from it). Reading this brief discourse alongside that verse shows the same image doing very similar work in two different contexts.
