prāṇāpāna-gatī ruddhvā prāṇāyāma-parāyaṇāḥ||29||

Meaning : Those who seek Me by mastering the subtle energy within them. Through the sacred practice of prāṇāyāma, they control the flow of breath—offering inhale into exhale and exhale into inhale—thus harmonizing the life force. Such focused control leads them to inner stillness and spiritual elevation.
