Avataṃsaka Sūtra · the Flower Ornament

An enormous, hallucinatory scripture in which every particle contains every world and every moment contains every time — and where the image of Indra's net is set out: a net stretching infinitely, a jewel at each knot, each reflecting all the others including the reflections.

The home of this door's deepest true rhyme with the Tree — mutual containment without limit.
