Chapter 8 · The Imperishable Absolute · Krishna said
Bhagavad Gita 8.21 — The supreme abode
अव्यक्तोऽक्षर इत्युक्तस्तमाहुः परमां गतिम्। यं प्राप्य न निवर्तन्ते तद्धाम परमं मम ॥
avyakto'kṣara ityuktastamāhuḥ paramāṃ gatim | yaṃ prāpya na nivartante taddhāma paramaṃ mama ||
Meaning
That unmanifest is called the Imperishable, and is said to be the highest goal. Reaching it, none return — that is my supreme abode.
