When two people love each other . . . they discover a unity that is more than a mere merging . . . [it is a] third body that these two lovers share. The third brings to mind the Holy Spirit, the unifying force that is beyond all notions of right and wrong, good and bad. Its symbol is the white dove of peace, the peace that passes understanding. The mind, which is bound by the laws of duality, can never grasp the domain that transcends the opposites. That domain is a third force, and its signature is a feeling of spaciousness, for it can include everything.
