This ether is the honey of all beings, and all beings are the honey of this ether. Likewise this bright, immortal person in this ether, and that bright, immortal person existing as heart-ether in the body (both are madhu). He indeed is the same as that Self, that Immortal, that Brahman, that All.

In plain words: The open sky-space (ether) and all beings nourish each other like honey. The shining, deathless presence in that vast space is the same one that lives in the small space of our heart. Both are the one Self, Brahman, which is everything.
