If we take this combination of blood, bone, muscles and veins and urine and stool is the life, then he, you are no better than the cats and dogs. Sa eva go-kharaḥ (SB 10.84.13). Go-kharaḥ. Go means cow, and kharaḥ means ass. So the ass is also thinking like that; a cow is also thinking like that. If you are thinking like that, then you are . . . So one has to learn what he is.
Then Sanātana Gosvāmī said,
- kṛpā-kari' yadi more kariyācha uddhāra
- āpana-kṛpāte kaha 'kartavya' āmāra
- (CC Madhya 20.101)
"My Lord, Caitanya Mahāprabhu, very kindly You went to my place and You have delivered me, so that after Your visit I decided to resign from the government service, and I have come to You. So You have delivered me from the pitfalls of this materialistic way of life. Now tell me what is my duty." This is student. This is disciple. Approach a bona fide guru, a spiritual master, and abide by his orders and do accordingly. Then your life will be successful. And if you keep yourself in the darkness, that "I am very rich man, I am very learned man, but unfortunately, I do not know what I am," so what is the use? The Narottama dāsa Ṭhākura: vidyā-kule hi karibe tāra. So if you do not know yourself, then what your so-called education and high family, high nationality, will help you? Nature's law is different. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). If you do not cultivate spiritual knowledge, if you remain like cats and dogs, then prakṛti, nature, will give you the cats' and dogs' body next life. Suppose you become very big businessman and you have got nice, very big balance and so on, so on, but by your activities you remain like a dog mentality is, then you are going to get the body of a dog. Yaṁ yaṁ vāpi smaran loke tyajaty ante kalevaram (BG 8.6). The test is at the time of death. At the time of death, if my mentality is different, so according to that mentality I shall get the body. This is called transmigration of the soul. There is no teaching of this science throughout the whole world, and we are trying to educate people. Of course, it is very difficult to understand, but this is the science, that there is transmigration of the soul. And if we do not take care of this, that "What I am going to become next life?"—if you simply waste your time simply on the matter of eating, sleeping, mating and defense, then we are wasting our time. This is the subject matter of Kṛṣṇa consciousness.
