Bhagavad Gita · Chapter 8: The Imperishable Absolute
Bhagavad Gita 8.2
अधियज्ञः कथं कोऽत्र देहेऽस्मिन्मधुसूदन ।
प्रयाणकाले च कथं ज्ञेयोऽसि नियतात्मभिः ॥
adhiyajñaḥ kathaṃ ko'tra dehe'sminmadhusūdana | prayāṇakāle ca kathaṃ jñeyo'si niyatātmabhiḥ ||
Who is the basis of sacrifice here in this body, Krishna, and how? And how are you to be known at the hour of death by those who are self-controlled?
Modern context
The second question is the one that matters most to Arjuna: how is the divine known at the hour of death? It is the question every human being eventually asks. What happens at the end, and how should one meet it? Most cultures avoid the subject until it is unavoidable. The Gita puts it at the centre of a whole chapter, and treats preparing for death as part of learning how to live.
