Spiritually advanced means gradually you forget that, "I am this material body." "I am Kṛṣṇa's. I am Brahman." That is spiritually advanced. And material advance means "I am this body." "I am American," "I am Indian," "I am brāhmin," "I am kṣatriya," "I am man," "woman." This is materially advanced. Both ways. This human form of life . . . because it is not animal life. Always remember that I'm not animal; I'm now human being. So I can utilize . . .
These things will be explained in this chapter, how I can utilize this body. Both ways I can utilize. If I simply limit myself with the bodily necessities of life, just like the animals, eating, sleeping, sex intercourse, and defense—these are common to the human body and the cats' and dogs' body. But because I am human being, I can utilize my body in a different way. The cats and dogs cannot do. That is the difference between a human being and an animal. If you don't utilize my body as human being, then I am no better than cats and dogs.
Actually I am cats and dogs. If we simply limit myself how to eat very nicely, how to sleep very nicely, how to have sex intercourse very nicely and how to defend myself very nicely, then you are no better than animal. But this is the business of the animals. The ani . . . animal cannot be invited to become Kṛṣṇa conscious. That is not possible. Even if he's invited, he cannot sit down, he cannot hear.
Therefore those who are very much advanced in animal propensities, they cannot take part in this Kṛṣṇa consciousness movement. Those are . . . those who are, to say frankly, no better than animals, they cannot take any interest in the Kṛṣṇa consciousness movement. That is not possible. Therefore Kṛṣṇa says who can take. He says . . . we take from Kṛṣṇa all the words; you don't believe me. Kṛṣṇa says that:
- yeṣāṁ tv anta-gataṁ pāpaṁ
- janānāṁ puṇya-karmaṇām
- te dvandva-moha-nirmuktā
- bhajante māṁ dṛḍha-vratāḥ
- (BG 7.28)
So animal life means sinful life. Animal life. Even this human form of life is also sinful unless we come to the Kṛṣṇa consciousness platform. We come to the . . . animal life means sinful life. If I act as sinful, like hogs and dogs . . . just like if I don't discriminate of eating. Just like the hogs, they have no discrimination. They accept even stool: "Come on. I shall eat." You get the body of hogs or dogs. And if you utilize this body according to the śāstra to purify it . . .
Because human body is meant for purification. Yasmāt śuddhyet sattvam. That is the given, instruction given by Ṛṣabhadeva. Tapo divyaṁ putrakā yasmāt śuddhyet sattvaṁ yena . . . śuddhyet sattvaṁ yasmād brahma-saukhyam anantam. Nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhati viḍ-bhujāṁ ye (SB 5.5.1). He advised, instructed His sons, "My dear sons, don't use this body like the hogs and dogs, whole day and night searching after stool, eating, for eating. Don't use this."
