At Grandfather Gandhi's service village, each day is filled, from sunrise to sunset, with work that is done for the good of all. The villagers vow to live simply and non-violently. Arun Gandhi tries very hard to follow these vows, but he struggles with one of the most important rules: not to waste.

How can throwing away a worn-down pencil hurt anyone? How can wastefulness lead to violence? With the help of his grandfather, Arun learns how every wasteful act, no matter how small, affects others. And in time he comes to understand the truth of his grandfather's words: "Be the change you wish to see in the world."
