"Our body and this complex world around us is meant to reveal and display the Self variously. Spiritual seeking lies in looking for That which animates the body. Turn the mind and intelligence inward to their very Source. Let the thoughts make you search for the thinking substance, the thinker. Only then the mystery of the Self will be unveiled."
