Chapter 8 - Verse 22 — Ancient Knowledge

पुरुषः स परः पार्थ भक्त्या लभ्यस्त्वनन्यया ।
यस्यान्तःस्थानि भूतानि येन सर्वमिदं ततम् ॥ २२ ॥

puruṣaḥ sa paraḥ pārtha bhaktyā labhyastvananyayā .
yasyāntaḥsthāni bhūtāni yena sarvamidaṃ tatam .. 22 ..

Now, that Highest Puruṣa, O son of Pṛthā, within Whom all beings dwell, by Whom all this is pervaded, is attainable by exclusive devotion

Read the commentary

Puruṣa is so called because He rests in the body, or because He is full. Than Him none is higher. He is attained by exclusive devotion, by jnana or knowledge of the Self. All the created beings abide within the Puruṣa; for, every effect rests within its cause; and by that Puruṣa the whole world is pervaded.

The Paths of Light and Darkness.

Now it is necessary to speak of the Uttaramarga, ‘the Northern Path’, the Path of Light by which the Yogins just spoken of attain to Brahman,—those Yogins who meditate here on Brahman as inhering in the Praṇava, in the syllable ‘Om’, and who attain to moksha later on.* And this will be taught in the section beginning with viii. 23. The path of return is also described, only with a view to extol the other path.

At the end of the kalpa.
