सर्वाणीन्द्रियकर्माणि प्राणकर्माणि चापरे । आत्मसंयमयोगाग्नौ जुह्वति ज्ञानदीपिते ॥२७॥
sarvāṇīndriya-karmāṇi prāṇa-karmāṇi cāpare ātma-saḿyama-yogāgnau juhvati jñāna-dīpite
sarvāṇi — of all; indriya — the senses; karmāṇi — functions; prāṇa-karmāṇi — functions of the life breath; ca — also; apare — others; ātma-saṁyama — of controlling the mind; yoga — the linking process; agnau — in the fire of; juhvati — offer; jñāna-dīpite — because of the urge for self-realization.
Some, inspired by knowledge, offer the functions of all their senses and their life energy in the fire of the controlled mind.
The yoga system conceived by Patañjali is referred to herein. In the Yoga-sūtra of Patañjali, the soul is called pratyag-ātmā and parāg-ātmā. As long as the soul is attached to sense enjoyment it is called parāg-ātmā, but as soon as the same soul becomes detached from such sense enjoyment it is called pratyag-ātmā. The soul is subjected to the functions of ten kinds of air at work within the body, and this is perceived through the breathing system. The Patañjali system of yoga instructs one on how to control the functions of the body’s air in a technical manner so that ultimately all the functions of the air within become favorable for purifying the soul of material attachment. According to this yoga system, pratyag-ātmā is the ultimate goal. This pratyag-ātmā is withdrawn from activities in matter. The senses interact with the sense objects, like the ear for hearing, eyes for seeing, nose for smelling, tongue for tasting, and hand for touching, and all of them are thus engaged in activities outside the self. They are called the functions of the prāṇa-vāyu. The apāna-vāyu goes downwards, vyāna-vāyu acts to shrink and expand, samāna-vāyu adjusts equilibrium, udāna-vāyu goes upwards – and when one is enlightened, one engages all these in searching for self-realization.
