The physical world is for our pleasure. Spiritual growth comes through grappling with the mundane world in a way that uplifts and elevates. You didn't really want any more, but you finished it anyway. Human beings are pleasure-seekers.
Pleasure is energy.
The more pleasure we have, the more power we have for living. But while physical pleasure is an essential part of enjoying life, we must learn to harness it. When a wine connoisseur takes a glass of wine, he'll sniff it first, then put a little into his mouth, swish it around, and if it passes his approval, swallow it. Or it may be relaxing in a hot sauna, drinking a glass of champagne, and then polishing off a steak and French fries. The first time you try something new, you focused intently on what pleasure you're having.
