I wonder what folk think about those wonderful pictures that appear as, say, a man and woman in profile facing each other as the white space, and the black space between them is an urn. Or a duck in the vertical plane which is a rabbit in the horizontal plane when tilted 90deg.
Would any sacred space be considered as similar?...one can quite easily 'see' what it means to them, but for someone else, something else has to be focused upon.
That's kinda like the Sufi quote and the radio reference where one's 'noise' has to be identified and the actual 'sound' may reveal itself.
And here I am writing this in the shade while just a few feet away is sunshine...guess I'll make a jump to the left ;)
