The Heart of the Mahāyāna
Where The Buddha's Own Words reads the earliest layer of scripture, this course reads the Mahāyāna's own — the sūtras that shaped Buddhism across China, Japan, Korea, Tibet, and Vietnam. Same format: lecture notes, primary text, discussion, assignment — but the texts themselves are stranger, denser, and, in places, deliberately built to break ordinary logic before rebuilding it on more honest ground.
We start with the shortest scripture in the entire Mahāyāna canon and, arguably, its single most important text: the Heart Sūtra — Prajñāpāramitā-hṛdaya, "the heart of the Perfection of Wisdom." At roughly 260 Chinese characters, it is short enough to memorize in an afternoon and dense enough to spend a lifetime unpacking.
A note on the text: the full bilingual translation, reading guide, and self-check quiz for the Heart Sūtra already exist as their own dedicated page in Ru-Yi's Mahāyāna Sūtras collection — Xuanzang's 649 CE Chinese text (public domain) alongside an original English translation. This course session doesn't repeat that page; it wraps a class session around it.
- Read the Heart Sūtra's wall of negations without the two classic misreadings — nihilism ("nothing exists") and word-games — landing instead on what the text actually claims.
- Apply the negation framework from Collected Topics Session 5 to a real, load-bearing scriptural text — not just a logic exercise, but a genuine reading tool.
- Explain the line "form is emptiness, emptiness is form" accurately, including why the sūtra insists on running the equation in both directions.
- Follow the Diamond Sūtra's "is not X, that is why it is called X" formula through Sections 1–32, from giving without dwelling to the bodhisattva's vow restated — then watch the same "no fixed nature" teaching turn into 141 wishes for all beings in the Chapter of Pure Conduct.
Same five-part rhythm as The Buddha's Own Words.
All four sessions are live.
- Nothing to buy. Every primary text is free on this site, in the Mahāyāna Sūtras collection.
- Collected Topics is recommended, not required. Session 1 specifically reuses the negation lesson from its Session 5 — the course still works without it, just with slightly more explanation.
- Comfort with paradox. These texts are built to unsettle tidy answers before they offer better ones.
