If one is interested simply with the four principles of the bodily necessities, āhāra-nidrā-bhaya-maithuna-eating, sleeping sex and defense, they are called viṣayīs. Viṣayiṇām... Viṣayaḥ khalu sarvataḥ syāt. If viṣayī means rich man, then why the śāstra says viṣayaḥ khalu sarvataḥ syāt: the enjoyment of these four necessities of body, it is available everywhere? The sparrow, he's also enjoying viṣaya. There is a male and female, and they are jumping from one tree to another, from here to there. And as soon as they require, they are enjoying sex and eating something. So eating, sleeping, mating, this is going on. That viṣaya is available... I have seen at night a small insects, they are also enjoying eating, sleeping, mating. A small, very small ant is captured. Jīvo jīvasya jīvanam. One life is meant for being eaten by another life. You can see, very small. He has got all the same tendencies. So viṣayaḥ khalu sarvataḥ syāt. So one has to become free from this viṣaya. Viṣayiṇāṁ sandarśanam atha yoṣitāṁ ca hā hanta hanta viṣa-bhakṣaṇato 'py asādhu (CC Madhya 11.8). That is Caitanya Mahāprabhu's... So we should be very careful. Viṣayiṇām, a devotee, if he thinks, "Oh, here is a nice woman. If I could enjoy her," or "Here is a nice man. If I could enjoy him." This is viṣayī. Viṣayiṇāṁ sandarśanam. To see one woman is not dangerous, but to think of enjoying, that is dangerous. Similarly, to see one man is not dangerous—you cannot avoid that; you are on the street here—but to see with the spirit of enjoyment, that is dangerous.
So we should be very careful. That requires, I mean to say, training, very strong training in Kṛṣṇa consciousness. Unless one is strongly in Kṛṣṇa consciousness, that long habit of enjoying spirit cannot be given up.
