Much to our relief, we discovered we did not need to consider another's conception of God Our own conception, however inadequate, was sufficient to make the approach and to effect a contact with Him. As soon as we admitted the possible existence of a Creative Intelligence, A Spirit of the Universe underlying the totality of things, we began to be possessed of a new sense of power and direction, provided we took other simple steps. We found that God does not make too hard terms with those who seek Him. To us, the Realm of Spirit is broad, roomy, all inclusive; never exclusive or forbidding, to those who earnestly seek. It is open, we believe, to all men.
