Bhagavad Gita · Chapter 8: The Imperishable Absolute

Bhagavad Gita 8.10

prayāṇakāle manasācalena bhaktyā yukto yogabalena caiva | bhruvormadhye prāṇamāveśya samyak sa taṃ paraṃ puruṣamupaiti divyam ||

who at the time of death, with an unmoving mind, filled with devotion and the power of yoga, fixes the life-breath firmly between the eyebrows, reaches that supreme divine Person.

Modern context

Three things together carry a person to the highest at the end: an unmoving mind, devotion, and the strength built by yogic practice. The description of fixing the breath between the eyebrows comes from the meditative techniques of the time. The deeper point does not depend on the technique. Steadiness, love and discipline, each built over years, are what a person will have available in their last moments.
