Chapter 8, Verse 21
Part of 8: Akṣhar Brahma Yog — अक्षरब्रह्मयोगअव्यक्तोऽक्षर इत्युक्तस्तमाहुः परमां गतिम्। यं प्राप्य न निवर्तन्ते तद्धाम परमं मम॥
avyakto ’kṣhara ityuktas tam āhuḥ paramāṁ gatim yaṁ prāpya na nivartante tad dhāma paramaṁ mama
What is known as the Unmanifested and the Imperishable, That is said to be the highest goal. Those who reach It do not return (to this Samsara). That is My supreme abode (place or state).
Para Brahman is called the Unmanifested because It cannot be perceived by the senses. It is called the Imperishable also. It is allpervading, allpermeating and interpenetrating. Para Brahman is the highest Goal. There is nothing higher than It. This is the true nondual state free from all sorts of limiting adjuncts. The attainment of Brahmaloka (the region of the Creator) etc., is inferior to this. Only by realising the Self is one liberated from Samsara. (Cf. XII.3?XV.6)
