That is this Brahman, without before or after, infinite, external, omnipenetrating, eternal, omnipresent, subtle, essence of being, true Brahman.

Repetition of verse 4.9, emphasizing the importance of this description. In the Vedic tradition, repetition is teaching; what is repeated is what must be internalized. In our yoga practice, meditating on these epithets of Brahman is remembering our own nature: I have no before or after, not limited by time; I am omnipenetrating, not confined to body; I am subtle, not reducible to the gross; I am essence of being, not appearance. Each epithet is a portal to recognition.
