चित्तेन्द्रियाणां चिरनिग्रहेण श्वासप्रचारे शमिते यमीन्द्राः ।निवातदीपा इव निश्चलाङ्गाः मनोन्मनीमग्नधियो भवन्ति ॥ १८ ॥
In plain words
Mind and senses held in check over long years, the traffic of the breath brought to rest — and the masters of restraint sit like lamp-flames in a windless room: not a limb stirring, awareness sunk clean under into manonmanī.
Close to the Sanskrit
By the long restraint of mind and senses, when the moving of the breath has been quieted, the lords among the self-restrained, like lamps in a windless place, with unmoving limbs, become those whose awareness is sunk in manonmanī.
