आपानं ऊर्ध्वं उत्थाप्य प्राणं कण्ठादधो नयेत् । योगी जराविमुक्तः सन्षोडशाब्दवया भवेत् ॥ २.४७ ॥

āpānaṃ ūrdhvaṃ utthāpya prāṇaṃ kaṇṭhādadho nayet । yogī jarāvimuktaḥ sanṣoḍaśābdavayā bhavet ॥ 2.47 ॥

By raising the Apâna Vâyu and suppressing the Prâna Vâyu from the throat, the Yogî, liberated from old age, becomes as young as if he were 16.
