Continuation of the technique: inhaling through the left, exhaling through the right. This is the first form of nāḍīśodhana — purification of the energy channels.

The left inhalation/right exhalation pattern activates and balances energy flows. It is the basis of all advanced prāṇāyāma.

Purification of the nāḍīs is the immediate objective. When the channels are clean, prāṇa flows freely and meditative states arise naturally.
