Eknath Easwaran's Commentary
The will does not grow weak through neglect. Rather, we undermine it, usually through little indulgences, often concerning food. We say, “What does it matter?” What matters is the effectiveness of our will.
When we sneak down to the refrigerator at midnight, it’s a guerilla raid on the will. As we find the slice of pizza, we ask, “After all, who’s to know?” No one may know, but, to use Ruysbroek’s language, the goodness of our will is a little more fragile.
Our will can withstand a lot of this kind of attack, but eventually it may go into hibernation. Then, the answer is to rouse it out of its sleep by resisting everyday temptations where food is concerned.
