sarva-bhakṣyo ’pi yuktātmā
nādatte malam agni-vat
The word udara-bhājana indicates that a saintly person eats only to keep body and soul together and not for sense gratification. One should eat palatable foodstuffs to maintain one’s mind in a cheerful mood; however, one should not eat luxuriously, because this will cause sex desire and laziness. A saintly person is always a perfect gentleman and is never greedy or lusty. Although māyā tries to defeat him by offering different material allurements, ultimately these attractive material features are themselves defeated by the spiritual power of a saintly person. Thus, one should never disrespect a spiritually advanced personality but should worship him reverentially. To carelessly approach a Kṛṣṇa conscious personality is just like carelessly approaching fire, which immediately burns if not handled properly. The Lord does not excuse mistreatment of a pure devotee.
