1 is you, 2 is one half of a Duality and 3 is the other, opposite side of a Duality.

1, 2 and 3 are all real.  Knowing 1, 2 and 3 and knowing which is primary, best and Loving is Wisdom. Living 1, 2 and 3 wisely is Grace. Knowing, even a little bit, that they are all three utterly integrated throughout the cosmos is bliss.
