Vijnana Bhairava Tantra · Dharana 31 · Verse 54
Body or world thinning to nothing
A slower dissolving than fire. Take either the body or the world and let it grow subtler by degrees—dense, then finer, then finer still—until there is nothing left to hold. Do this without drama. You are watching solidity leave, the way mist leaves a field. When the last trace of the object is gone, remain with what is looking. That remaining is the practice.

Contemplate the elements of your own body, or of the world, as subtle and ever subtler, dissolving back into their source. At the end, the Supreme Goddess is revealed.
