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.
