Mr. Loomis: Could I ask a question? I look at this room and my senses are gratified by this room, by that painting, by beautiful flowers, by the chanting of Hare Kṛṣṇa is pleasing to my ear, and I have to feel that my senses are able to help my spirit, or else there will not be this beauty in this room. But I don't understand very well when sense gratification is helpful and when it is not.
Prabhupāda: Sense gratification is never helpful. That is described in the Śrīmad-Bhāgavatam, that kāmasya nendriya-prītir (SB 1.2.10). Sense gratification is required as far as . . . as little as possible. Otherwise, not for sense gratification. Just like sleeping. Sleeping is required because this material body requires some rest. But not that we shall sleep twenty-four hours or twenty hours and enjoy, as in this country sometimes they enjoy sleeping. But sleeping is wasting time. So long we shall sleep we cannot do anything good work. Therefore it should be minimized. You cannot avoid sleeping altogether. That is not possible. But it should be accepted to the minimum extent. That is not possible. But it should be accepted to the minimum extent. That is called tapasya, or advancement of spiritual life. Eating, sleeping, sex and defense. Āhāra-nidrā-bhaya-maithuna. They're required. So long we have got this body, we require to eat something, we require to sleep sometimes, we require a little sense gratification, and we require defense. But it should be minimized, not increased. That is tapasya. In the human life this is possible, this is possible. Nidrāhāra-vihārakādi-vijitau. One can conquer over these things, by practice. The more we minimize this āhāra-nidrā-bhaya-maithuna, this means we are advanced in spiritual taste. It is practice. My, my personal life, I don't sleep at night. And nowadays, at most, one hour. Yes. But I take rest in the daytime, at least two to three hours.
