A saintly person should go from door to door accepting just a little bit of food from each family.
Sometimes a honeybee is attracted by the extraordinary aroma of a particular lotus flower and lingers there, neglecting his usual activity of flying from flower to flower. Unfortunately, at sunset the lotus flower closes, and thus the infatuated honeybee is trapped. Similarly, a sannyāsī or brahmacārī may discover that excellent foodstuff is available at a particular house, and therefore, instead of wandering from place to place, he may become a veritable resident of such a well-fed household. Thus he will become bewildered by the illusion of family life and fall down from the platform of renunciation. Therefore, a saintly person should accept only enough food to keep his body and soul together. He should go from door to door accepting just a little bit of food from each family.
