Thirtieth dhāraṇā. Of disarming simplicity. Tanūdeśe — in any place of the body. Any. The knee. The shoulder. The little finger. Śūnyataiva — the void itself. Kṣaṇamātram — only for an instant.

You need no hours of meditation. You need no special place of the body. One instant of void perception at any bodily point suffices. Nirvikalpam nirvikalpasvarūpaḥ — free of constructs, you become your own nature free of constructs.

The technique is almost absurdly easy to describe and extraordinarily difficult to realize. Because kṣaṇamātram — a single instant — of true void perception requires that mind stop completely. And when it stops, even for a blink, reality reveals itself.
