So this kind of hard labor simply for satisfying the tongue and the genital, that is hog civilization. That is warned by Ṛṣabhadeva, nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate (SB 5.5.1). Why? Kāmān means eating, sleeping, sex life and defending. These are kāmān, bodily necessities of life. As soon as you will get this material body, you will have to eat. In the spiritual body there is no eating. Eating means to sustain this material body. You will find many saintly persons. Practically, they do not eat.
Raghunātha dāsa Gosvāmī, he was eating at Rādhā-kuṇḍa, every two.... After two, three days after, he was eating little butter, just to satisfy. Practically no eating. Raghunātha dāsa Gosvāmī was a very rich man's son. His father's income was twelve lakhs of rupees in those days. So he adopted this austerity at Rādhā-kuṇḍa.
So actually that is the fact, that in the spiritual life there is no eating, no sleeping, no sex life, no defense. These are all material necessities. So material necessities, we have day and night for sense gratification, material satisfaction, then where is the difference between hogs and dogs and human beings? And this is going on. We are accepting this civilization as advanced. The more you have got facility for sense gratification, it is to be understood that you are advanced. So that advancement means to give satisfaction to the body.
