The whole system on one page

Map of the Thirty Verses

The text is short — thirty stanzas — but densely structured. This page lays out the architecture so you can hold all 30 verses in mind at once before diving into individual readings. Each diagram is paired with a short reading guide and a list of the verses it draws on.

The three transformations

The three transformations of consciousness as a layered information system. Verse 2 names the layers; the rest of the text unpacks how impressions flow between them.

How to read it Three boxes, stacked. Read bottom-up. The bottom box (ālaya) is the slowest, deepest layer — an append-only store of karmic seeds. The middle box (manas) is an always-on reader that treats the store as belonging to "I". The top box is the six moment-to-moment sense streams.

The arrows are the whole point. Upward arrows show how the lower layers condition the upper ones — ālaya replays seeds, manas colors what the senses receive. Downward arrows show the return path: every act of cognition writes new impressions back down into the store. One transformation, three modes; not three separable modules.

The seed–impression cycle

Karma in Yogācāra is not bookkeeping but a feedback loop: actions deposit impressions that become seeds that ripen into the next round of experience — which conditions the next action.

How to read it A diamond of four nodes, traversed clockwise. Start at the top: an action (karma) leaves an impression (vāsanā) on the store; that impression settles into a seed (bīja); the seed eventually ripens (vipāka) into the next experience — which becomes the condition for the next action. Loop closes.

The diagram corrects a common Western misreading: karma in Yogācāra is not moral bookkeeping by an external auditor. It is the structural feedback inside a single mental stream. The person who acts and the person who later reaps are connected by a continuous chain of seeds, not by a ledger.

Sense consciousnesses as waves

Verse 15: the five sense-consciousnesses (and the thinking mind) arise on the substrate like waves on water — transient, condition-dependent, never separate from what they arise on. A pub/sub topology, but where the consumers are themselves made of the substrate.

How to read it The horizontal band is the ālaya — the substrate. The humps are the six sense-consciousnesses: eye, ear, nose, tongue, body, and the thinking mind. Notice they are made of the band, not lined up next to it. The wave is what the water is doing in a given moment under given conditions.

The image carries four claims at once: same stuff (no separate soul-substance behind perception), transient (every wave is a finite event), conditional (no condition, no wave), and concurrent (several waves at once on one surface). When conditions drop — deep sleep, fainting, the meditative attainments named in verse 16 — the surface goes flat.

The three natures

The three natures (trisvabhāva): the dependent (what actually arises by conditions) becomes either the imagined (when we project self/other onto it) or the realized (when we see it stripped of that projection). Same substrate, different relation.

How to read it Three nodes on a triangle, but they are not three independent things. The bottom-left node, the dependent nature (paratantra), is the only one that actually arises. The top node, the imagined (parikalpita), is what gets falsely projected onto it. The bottom-right node, the realized (pariniṣpanna), is the dependent nature seen as such — stripped of the projection. Same substrate, different relation.

This is the move that lets Yogācāra say "everything is mind" without sliding into solipsism. The dependent nature is real; what is unreal is the imagined-self overlay we paint on top of it. Liberation is not escape from the dependent — it is clearing the imagined off it.

Structure of the text

Verses	Section	What gets established
1	Thesis	Self and other are events inside a transformation, not things outside it.
2–4	Layer 1: Ālaya	Store consciousness as the karmically-neutral substrate; "like a river flowing."
5–7	Layer 2: Manas	The reader of the substrate that mistakes it for "I"; four afflictions always present.
8–14	Layer 3: Sense consciousnesses	The six sense streams and their associated mental factors, beneficial and afflictive.
15–16	Dynamics	How the senses arise on the substrate; when thought ceases.
17–19	"Projection only"	The central claim: what is conceptualized does not exist; everything is vijñapti-mātra.
20–25	Three natures	Imagined, dependent, realized; threefold absence of self-nature.
26–30	The turning	The path from grasping to non-grasping; the overturning of the root; the Dharma body.
