Where on earth does heart come into all this? The heart is simply container, of all that is, but especially of time. The heart is the Universe, the one space, the unifier and unity that magically transforms contradiction into paradox (never orthodox). So the heart must be huge, which is why Buddhists work on compassion and Christians work on love: because it is love and compassion that expand the heart sufficient to contain not just my own world but all others too. The heart is eminently tolerant because by accepting all difference it sees no difference: it possesses the ground upon which all is rooted, it is the source of all essence.
