Bhagavad Gita Chapter 8, Verse 9
प्रयाणकाले मनसाचलेन भक्त्या युक्तो योगबलेन चैव | भ्रुवोर्मध्ये प्राणमावेश्य सम्यक् स तं परं पुरुषमुपैति दिव्यम् ||
prayāṇa-kāle manasā acalena bhaktyā yukto yoga-balena caiva bhruvor madhye prāṇam āveśya samyak sa taṁ paraṁ puruṣam upaiti divyam
At the time of death, with a steady mind, endowed with devotion and the strength of yoga, fixing the life force between the eyebrows, one attains the supreme divine Person.
Krishna describes the practice at death: 'Prayana-kale manasa acalena'—at the time of death (prayana-kale), with a steady (acalena) mind (manasa). 'Bhaktya yukto yoga-balena chaiva'—endowed (yukta) with devotion (bhaktya) and the strength (balena) of yoga. 'Bhruvor madhye pranam avesya samyak'—fixing (avesya) the life force (pranam) properly (samyak) between the eyebrows (bhruvor madhye). 'Sa tam param purusham upaiti divyam'—he (sah) attains (upaiti) that supreme (param) divine (divyam) Person (purusham). This verse describes the yogic practice: steady mind, devotion, yoga strength, and focusing the life force at the spiritual center (between the eyebrows). This is the culmination of practice—all the daily cultivation comes together at death. The steady mind comes from daily practice. The devotion comes from constant remembrance. The yoga strength comes from regular practice. This is how you remember Krishna at death—with all the preparation you've done during life.
