Anuloma viloma: how to practice

1 : 4 : 2 — Inhale → Hold → Exhale

Sit comfortably, with one hand in vishnu mudra.

1. Block right nostril with thumb, inhale through left
2. Hold (both nostrils closed)
3. Block left nostril, exhale through right
4. Keep hand in position, inhale through right
5. Hold
6. Exhale through left

This is one round.

You might find that one nostril may feel more open, but with time, this will balance out.
