Caturthopadeśaḥ (Samādhi) · Verse 15

अमरी-धारणा-कालं यः करोति सदा शुचिः | सिद्धिं लभति पूर्णां स मृत्युं जयति योगवित्

amarī-dhāraṇā-kālaṃ yaḥ karoti sadā śuciḥ | siddhiṃ labhati pūrṇāṃ sa mṛtyuṃ jayati yogavit

He who always practices concentration on the immortal nectar, remaining pure, achieves complete perfection;that connoisseur of yoga conquers death.

This verse introduces the practice of amarī or amarolī, related to the nectar of immortality:

Amarī-dhāraṇā — concentration on the immortal (amara).It refers to the practice of retaining and absorbing the amṛta (nectar) that flows from the brain, preventing it from being consumed by the digestive fire.

Sadā śuciḥ — always pure.Physical and mental purity is a requirement.The practice requires a body and mind prepared through previous disciplines.

Siddhiṃ pūrṇām — complete perfection.Not partial achievements but total realization.

Mṛtyuṃ jayati — conquer death.This is the ultimate goal of haṭha yoga according to many texts.Not necessarily physical immortality, but transcendence of the cycle of birth and death.

The Bihar School interprets mṛtyuñjaya (conquest of death) on multiple levels: physical longevity, overcoming the fear of death, and realization of the immortal Self who is never born or dies.

Mallinson notes that these nectar conservation practices are central to the Nāth tradition.
