निरङ्कुशानां श्वसनोद्गमानां निरोधनैः केवलकुम्भकाख्यैः ।उदेति सर्वेन्द्रियवृत्तिशून्यो मरुल्लयः कोऽपि महामतीनाम् ॥ १३ ॥
In plain words
The breath keeps surging up, ungoaded, answering to nothing. Check those surges by the holding they call kevala-kumbhaka, and for the great-minded something rises that has no name: the breath dissolves, and not one movement of the senses is left.
Close to the Sanskrit
By the restraints named kevala-kumbhaka, of the uncurbed upsurges of the breath, there arises — void of all sense-activity — a certain dissolution of the vital air, for those of great mind.
