Nourishment refers to more than a healthy diet. It is the care-giving function. Eating properly implies care for oneself; providing healthy meals in the home is a sign of caring for the family. The writer of a great book or composer of an inspiring piece of music also provides nourishment, by caring deeply about the quality of his or her work and offering it to the world.
We can know others by observing what they choose to nourish in their lives. Do they properly feed and develop their bodies? Do they cultivate their spirits, their intellects, their moral values? Do they nourish and care for those around them? If so, to whom do they devote their energies? The most successful people are temperate in eating and drinking, thinking and dreaming. They strengthen the world by nurturing everyone's higher nature.
Pay heed to your thoughts and impulses, ignoring those that undermine a healthy and persevering attitude. A wise person is temperate in the consumption of food and drink, because to be otherwise only leads to discomfort; the fact that temporary pleasure may precede the discomfort does not influence the person of mature character. In the same way, be discriminating in your words and actions, lest a desire for temporary advantage lead you to cause pain for yourself or others. Enrich your character and you will naturally nourish everyone around you.
