A saintly person should not store foodstuffs acquired by begging.

A saintly person should not think, “This food I will keep to eat tonight and this other food I can save for tomorrow.” In other words, a saintly person should not store foodstuffs acquired by begging. Rather, he should use his own hands as his plate and eat whatever fits on them. His only storage container should be his belly, and whatever conveniently fits into his belly should be his stock of food. Thus one should not imitate the greedy honeybee who eagerly collects more and more honey. One who is interested in making spiritual progress should avoid such a situation; however, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura points out that for the purpose of spreading Kṛṣṇa consciousness one may accumulate an unlimited amount of material opulence. This is called yukta-vairāgya, or using everything in the service of Kṛṣṇa. A saintly person who is unable to work in Lord Caitanya’s mission should practice austerities and collect only what he can hold in his hands and belly.
