Vijnana Bhairava Tantra · Dharana 8 · Verse 31
Point between the eyebrows
Sit with the eyes closed. Place attention at the point between and just above the eyebrows. Do not roll the eyes upward to look at it; that only creates strain. Lights may appear, or they may not. Either way, stay with the point. Visions are not required. Steady attention is.
Older line
Filling the head swiftly with that energy, breaking through by the bridge of the drawn-together brows, and leaving the mind free of thought, one rises to the all-pervading state above everything.
