'Food (anna) is better than power. Therefore if a man abstain from food for ten days, though he live, he would be unable to see, hear, perceive, think, act, and understand. But when he obtains food, he is able to see, hear, perceive, think, act, and understand. Meditate on food.

In plain words: Food is greater than strength. If a person goes without food for ten days, they may live but cannot see, hear, think or act properly; once they eat, these powers return.
