What “rainbow body” means in Dzogchen
In Dzogchen, a Tibetan Buddhist tradition, jalü—often translated as “rainbow body”—names an extraordinary culmination of practice. Its underlying idea is that ordinary perception mistakes reality for a collection of solid, separate things. Through sustained realization, a practitioner is said to recognize the mind’s empty, luminous nature: “empty” means lacking an independent, permanent essence, while “luminous” points to awareness rather than physical brightness.
Accounts of rainbow body apply that transformation to death itself. They describe the body becoming smaller or disappearing, sometimes with light or rainbows as signs. Within the tradition, this is understood not simply as a dramatic death but as the visible expression of realization: the elements that make up ordinary experience are said to resolve back into their subtle nature.
Why some remains matter in the story
Hair and fingernails figure in some accounts because they are treated as the body’s least vital, most material parts. Their presence can therefore be read, within the tradition, as a trace left after the rest of the body has dissolved. They are not presented as the source of the teaching; the central claim is that deep realization changes the practitioner’s relation to the body and to death.
Stories associated with Ayu Khandro belong to this religious and testimonial setting. Details such as a sealed tent or a sphere of light make the account vivid, but they should be understood as elements of the reported story, not as a mechanism established by ordinary observation. The lasting significance is the ideal the story conveys: liberation is imagined as so complete that even the boundary between spiritual realization and physical death appears to disappear.
