Vedic literatures enjoins that if you want sex life, then you become householder. You marry a nice girl, and then you have got very good responsibility. This, this concession, sex life, is allowed so that you have to serve the all others. That is the responsibility. Now there are four divisions of social order—brahmacārī, gṛhastha, vānaprastha and sannyāsa. The brahmacārī does not, I mean to say, earn anything.
They depend on the society. Sannyāsī—depend on the society. Vānaprastha—depend on the society. Only the householder who is living with wife and children, he has got the whole responsibility to provide these brahmacārī, vānaprastha and sannyāsī. You see? In India still, if a brahmacārī, if a sannyāsī goes to a householder, immediately offers something. So they do not want more, but they want little for their maintenance of this body and soul together. It is the duty of the householder.
So unless one becomes responsible householder, how he'll execute his responsibility? If he thinks, "Oh, what is the use of keeping a cow when the milk is available in the market? Oh, sex life is so cheap. Why shall I take the responsibility of marrying?" This is going on. This is going on. Just like cats and dogs.
So the cats and dogs cannot understand Vedānta philosophy. First condition. It is not meant for the cats and dogs; it is meant for human being. So we should be human being first of all. Then we shall try to understand. Our life is so wretched that it is less than cats and dogs, and we try to understand Vedānta philosophy. It is not possible.
So Caitanya Mahāprabhu says mukhya-vṛttye, direct meaning, as it is said. That is beauty of understanding. Janmādy asya yataḥ (SB 1.1.1): "The supreme source from which everything emanating, that is Brahman." What is the interpretation? There is no interpretation. Supreme . . . there must be some supreme source. That is quite philosophical and logical, that I have my . . . this bodily existence has a source, my father. My father has a source, his father, his father . . . go on. There must be one supreme source. That is God. Simple to understand. Is it very difficult to understand?
The supreme cause, He is God. Therefore Kṛṣṇa is described in Brahma-saṁhitā, sarva-kāraṇa-kāraṇam (Bs. 5.1). Kāraṇa means "cause," and sarva means "all." There are cause, cause, cause and effect, cause and effect, cause and eff . . . when you reach to the supreme cause, He's Kṛṣṇa. He's Kṛṣṇa. And Kṛṣṇa confirms it in the Bhagavad-gītā, ahaṁ sarvasya prabhavaḥ.
