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

In plain words: Truth (satyam) and all beings nourish each other like honey. The deathless presence in truth out in the world is the same one that lives in us as our truthfulness. Both are the one Self, Brahman.
