The Divine Self written by Robert E. Wilkinson

 'Spiritual Knowledge and Vision is dependent upon the realization of certain eternal truths, something which arises from the fount of the soul. It cannot be passed from one who has had it to another who has not. The sense of it however can be communicated in a structure or form which may inspire a recognition in others. To enter into the thoughts of the Spiritual Sages, one has to allow their words to sink into our souls to mold our thoughts and create their own reverberations in a sympathetic resonance. Their knowledge was accessible by listening to the old voices and allowing the "Sruti" (resonance) in the Soul to respond, to vibrate to the Vedantic hymn of knowledge and to allow that response to gradually gain in clarity, intensity and fullness.'
