One should retain the prāṇa as before, then exhale through iḍā. This removes phlegm disorders from the throat and increases the digestive fire.

This verse completes the technical description of ujjāyī. Pūrvavat kumbhayet indicates that the retention follows the same pattern described previously. The exhalation is performed through iḍā (left channel), though some commentators suggest it can also be done through both nostrils.

The benefits are śleṣmadoṣaharam kaṇṭhe — eliminating excess kapha (phlegm) from the throat. The characteristic sound of ujjāyī massages the mucous membranes and dissolves obstructions. This is especially useful for singers, speakers, and mantra practitioners.

Dehānalavivardhana — “increases the fire of the body” — indicates that ujjāyī generates internal heat (tapas). This heat not only improves physical digestion but also “cooks” subtle impurities, purifying the nāḍīs and preparing the practitioner for higher states of consciousness.
