Vijnana Bhairava Tantra · Dharana 22 · Verse 45
Three empty places
Sit with the eyes closed. Feel three regions at once as empty space: the space above the head, the base of the body, and the heart. Hold all three together, steadily, without moving between them. When attention is held this way, thought has nowhere to land, and a quiet that is free of thought begins to open.
Older line
Hold steady, all at once, the emptiness overhead, the emptiness at the root, and the emptiness in the heart. Free of thought in all three together, you wake into the state beyond thought.
