So this hearing process is recommended, that you should hear from a realized person who is sadācara-sampanna-vaiṣṇava. So who is a bhakta? Because you have to learn from a bhakta, so who is a bhakta? That is also described. So it is stated in the śāstras and the Gosvāmīs as sarvopādhi-vinirmuktaṁ tat-paratvena nirmalam (CC Madhya 19.170): "Anyone who has no more designation, and he is pure from material contamination." Upādhi means so long we think that "I am this body," that means I am decorated with this upādhi. So long we think that "I am Indian," "I am American," "I am brāhmaṇa," "I am Hindu," "I am Muslim," we are decorated with upādhi. Upādhi-śūnya is described in the Vedas, when one understands ahaṁ brahmāsmi. So there are two Brahmans: Para-brahman and ordinary Brahman. Para-brahman is the Supreme, vibhu, and ordinary Brahman, they are anu. Para-brahman is all-pervading, and Brahman is not all-pervading. So Kṛṣṇa says in the Bhagavad-gītā that, kṣetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata (BG 13.3). Kṣetra, kṣetrajña, when He was describing, kṣetra means this body, and kṣetrajña means the soul who knows about his body.
So there are two kṣetrajñas. One kṣetrajña is the jīva, soul, and another kṣetrajña is Paramātmā, Bhagavān. (break) . . . clearly distinguished by Kṛṣṇa that kṣetra-jñaṁ cāpi māṁ viddhi: "You are not only kṣetrajña." The jīva soul is kṣetrajñā. He knows, just like you know, I know, "It is my body." So there are two kṣetrajñas. One kṣetrajña I am. Just like I know this is my body, you know this is your body, but I do not know what is going on in your body, you do not know what is going on in my body. Therefore Kṛṣṇa says ca, eva, kṣetrajñaṁ ca api māṁ viddhi: "Not only you are kṣetrajña; I am also kṣetrajña because I am Para-brahman, or Supersoul." But what is difference between these two kṣetrajñas? The difference is that one kṣetrajña knows about his own body, but the super-kṣetrajña, He knows everyone's body.
