You have mastered masturbation when you care not about how much you endure or the pleasure gained from it, but what you are masturbating to. Masturbation is an act of appreciation, so it should only be performed while fantasizing about that which you truly like. Much like dogs marking their territories with urine, one should only masturbate to images he deems particularly creative or well-drawn to show his gratitude towards the artist, even when he has no carnal urges at the moment. That is a forlorn duty followed by few in those latter days of the Law. Indeed, the great masters of old weren't mistaken when they decreed, "Tell me what you masturbate to, and I'll tell you who you are."
