Now Amarolī: Discarding the first stream of water for excess pitta, and the last for being useless, the half-fresh stream is taken.In the Kāpālika school, this is called Amarī.

This verse introduces Amarolī, the most unorthodox of the three practices.Ambu-dhārā — stream of water — is a euphemism for urine.Amarolī involves the ritual use of one’s own urine as a yogic practice.

The specified technique: prathamāmbu-dhārāṃ vihāya — discard the first stream — because it is loaded with pitta (fire) and accumulated toxins.Antya-dhārām — the last spurt — is also discarded as niḥsāra (essenceless).Only madhya-dhārā — the middle stream — is used because it is śītala (cool, balanced).

Kāpālike khaṇḍa-mate — in the Kāpālika school — identifies the tantric origin of this practice.The Kāpālikas were extreme ascetics who used transgressive practices to transcend social and spiritual conventions.The term amarī (from nectar, immortal) connects purified urine with amṛta.

In Ayurveda, śivāmbu (Śiva water, urine) is considered medicine when used appropriately.This practice represents the extreme of yogic alchemy: transforming what is ordinarily considered waste into a vehicle of transformation.
