Fifth technique. Attention fixes upon nāsāgra — the tip of the nose. The breath, reduced to a subtle point (bindurūpeṇa), dissolves (vilīyate) in its own path (adhvani). It does not reach its destination. It evaporates along the way.

The nose-tip is the last point of contact between breath and the external world. It is a frontier. When attention concentrates there with sufficient precision, breath becomes increasingly subtle until it disappears. Not as apnea. As dissolution.

What remains is nirvirkalpaṃ tattvaṃ — the reality without mental constructs. And that, Bhairava says, is Bhairava himself. Not a deity. Not a concept. The naked reality that emerges when the apparatus of thought ceases.
