" our quest for intimacy we must move beyond our preoccupation with the physical and understand what each of the four aspects has to contribute to our relationships. Physical intimacy is limited. But emotional, intellectual, and spiritual intimacies are limitless, and relatively unexplored. And, truth be told, if you truly wish to experience the upper reaches of physical intimacy you must first explore and develop the depths of emotional, intellectual, and spiritual intimacy. "
