Prabhupāda: Blind man leading other blind men. If one has eyes to see, he can lead hundreds and thousands of men, "Please come along with me. I shall cross the road." But if the man leading, he is himself blind, how he can lead others? Andhā yathāndhair upanīyamānāḥ. So Bhāgavata, there is no comparison. There cannot be. It is transcendental science. Andhā yathāndhair upanīyamānās te 'pīśa-tantryām uru-dāmni baddhāḥ (SB 7.5.31). Īśa-tantryām, these blind leaders, they are bound up by the laws of material nature, and they are giving advice. What advice they can give? Then? Go on.
Pradyumna: "Almost all of them have a wrong conception of life, for they identify themselves with the gross and subtle material bodies, which they are not in fact."
Prabhupāda: This is their, I mean to say, less intelligence. Everyone thinks that "I am this body." Or little further off, one thinks, "No, I am not this body. I am mind." There are two bodies, one gross body made of these physical elements: earth, water, air, fire, sky, and another... Just like shirt and coat. You have got your coat, and within the coat there is shirt, and within the shirt, you are. This is gross example. Similarly, we have got this gross body and when the gross body is finished, then I keep myself in this mental body. That is called ghostly body. The ghostly body means one who is living in the subtle body. Ghost is a fact; it is not fictitious. So the subtle body carries me to another gross body. That is called transmigration of the soul. I must have some vehicle. The subtle body... Gross body is finished. That is gone. Now, the subtle body is there; therefore my mentality will create another gross body. If I am dog mentality, then I'll create another body, dog's body. And if I am God mentality, then I'll create another body like God.
This is the process. So, everyone has got full liberty how, what kind of body he's going to get next. So if you keep yourself in Kṛṣṇa consciousness, that consciousness, subtle body, then you are sure to get next life, if not in Vaikuṇṭha, at least you get a high standard life. That is confirmed in the Bhagavad-gītā, śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo 'bhijāyate (BG 6.41).
