Quote by Thomas Aquinas on spiritual joy and human longing

"The pleasures of sin exist. We cannot deny them. But we also dare not deny what follows in their wake: a voracious appetite, inflamed with eroticism, demanding more indulgence more often until a degenerative spiral captures the soul and drags us on a never ending descent into deeper patterns of immorality and illicit behaviour... Lust goes beyond the sexual. Lust can show itself in a variety of forms: covetousness, gluttony, drunkeness, power hunger, or unbridled ambition, to name a few" Edwin Louis Cole

"The most spiritual men, as the strongest, find their happiness where others would find their destruction: in the labyrinth, in hardness against themselves and others, in experiments. Their joy is self-conquest: asceticism becomes in them nature, need, and instinct. Difficult tasks are a privilege to them; to play with burdens that crush others, a recreation. Knowledge-a form of asceticism. They are the most venerable kind of man: that does not preclude their being the most cheerful and the kindliest." Friedrich Nietzsche
