The two birds represent humanity: they are mirror images of each other, each reflecting the other back to her/himself. They are graceful and beautiful, because they are creations of Brahm, which is represented by the heart. Their beaks harmoniously sip the nectar that sustains them from Brahm. In so doing, they are one, and one with Brahm ("we are we, we are God").
I am a field of awareness. Any thing beyond that is identification with form...
