Abstract
Haṭhayogic texts describe various techniques leading to the main goal of Haṭhayoga - physical immortality. One of these techniques is called "cheating death" (kālavañcana) and it is based on the ability of an advanced yogi to determine the precise moment of his death (kālajñāna).
He can acquire this knowledge from miscellaneous signs of death (ariṣṭāni). In this paper I have discussed the character, purpose and textual sources of these signs of death.
The study is based on Haṭhayogic texts written in Sanskrit, Bengali and Brajbhasha.
