Apaśyatām ātma-tattvam. Because they do not know, they have no information of the soul, they are talking about this body, or sometimes about this mind: philosophical speculation, concoction. One philosophy is theorizing something, another philosopher is theorizing something. Lots of literature, all nonsense, because it is mental speculation. I speculate in one way, you speculate in another way. You refute me, I refute you.
So therefore, these talks of the body and talks of the mind, there are varieties. Nṛṇāṁ santi sahasraśaḥ apaśyatām ātma-tattvam. Why they are engaged in so many talks? Because they do not know, apaśyatām. They have no vision of the soul, ātma-tattva. Gṛheṣu gṛha-medhinām. Gṛhamedhī, those interested simply to maintain this body, they are called gṛhamedhī.
Generally, atheist class, they have no interest in God. The atheist class . . . long, long ago, thousands of years ago, there was atheist also. Because there are two classes of men always within this world: atheist and theist, asura and deva, devatā. So not that atheist class men have developed at the present moment. It may be the number has increased, but atheist class of men were long, long ago also. There was Carvaka Muni, he was also called muni. Muni means mental speculator, or thoughtful.
So this Carvaka Muni, he also presented his philosophy, atheism, that ṛṇāṁ kṛtvā ghṛtaṁ yāvaj jīvet sukhaṁ jīvet: "So long you live, you live very joyfully by enjoying your senses." This is atheistic principle. And in India the sense enjoyment principle is based on ghee, clarified butter, because if they get butter, they prepare so many nice preparation. You have also learned how to do it. (laughter) In India there are varieties. If you sometimes go to India . . . in Delhi there are shops, many varieties of foodstuff, all from grains and fruits, that's all. Grain, fruits, ghee, sugar and salt. Varieties, hundreds. So eating, sleeping . . . the basic principle is eating, sleeping, mating. So Carvaka Muni says that, "Live very joyfully, and eat very nicely, enjoy your senses, finish your life." That is atheism.
