Physical pleasure is a sensual experience no different from pure seeing or the pure sensation with which a fine fruit fills the tongue; it is a great unending experience, which is given us, a knowing of the world, the fullness and the glory of all knowing. And not our acceptance of it is bad; the bad thing is that most people misuse and squander this experience and apply it as a stimulant at the tired spots of their lives and as distraction instead of a rallying toward exalted moments.
