is felt in the body, he should breathe in by the right
nostril.
64. After the interior of the body is quickly
filled with air, the nose should be closed tightly with
the thumb, the-ring finger and the little finger.
65. Having performed Kumbhaka as prescribed,
the breath should be exhaled through the left nostril.
This removes the [disorders arising from] excess of
wind, bile, and phlegm, and increases the [digestive]
fire in the body.
Bhastrikā Kumbhaka should be thus performed: Press the
left nostril with the ring and little fingers and, by the right nostril,
inhale and exhale like a pair of bellows. When tired, perform
Kumbhaka, inhaling by the right nostril, and exhaling by the left
nostril. Then press the right nostril, and inhale and exhale like
the bellows through the left nostril, etc. Thus go on alternately
till tired. This is one method: The other way of practising
it is to close the left nostril, and inhale as much as possible by the
right nostril, quickly close that nostril and then exhale gradually
through the left nostril. This should be done many times, and when
feeling tired one should inhale through the right nostril, perform
Kumbhaka, and exhale through the left nostril. Then this should
be done for the other nostril.

purifying, pleasant and beneficial. It removes the
obstructions caused by phlegm, etc. that exist at the
mouth of the Suṣumnā.
Sūryabhedana and Ujjāyī generate heat, and Sītkārī and
Śītalī are cool. Bhastrikā preserves an equable temperature.
Sūryabhedana primarily controls excess of wind, Ujjāyī phlegm,
Sītkārī and Śītalī bile, and Bhastrikā, all three.
