Viṣṇujana: ". . . confirm this concept of two kinds of souls by comparing them to two friendly birds sitting on the same tree. One of the birds, the individual atomic soul, is eating the fruit of the tree, and the other bird is simply watching his friend.
"Of these two birds, although they are the same in quality, one is captivated by the fruits of the material tree, while the other is simply witnessing his activity. Kṛṣṇa is the witnessing bird and Arjuna is the eating bird. Although they are friends, one is still the master and the other is the servant."
Prabhupāda: That is the eternal relationship. These are confirmed in Vedic literature, just like Śvetāśvatara Upaniṣad, Muṇḍaka Upaniṣad. The system is whatever is mentioned in the Vedas, that is authoritatively accepted. That is the Vedic understanding. If there is some evidence in the Vedas . . . just like in law court, if there is some section in the law book, then the lawyers, the judge, accept it, "Yes, it is like this."
Similarly knowledge. Vedas means knowledge. So perfect knowledge is there. Therefore if the evidence is there in the statement of Vedas, that is the proof. Śabda-pramāṇa. There are three kinds of evidences. Pratyakṣa, direct sense perception; and śabda-pramāṇa, evidence from the Vedic statement; and anumāna, aitihya, historical or hypothesis.
So out of all evidences, the evidence which is called . . . derived from Vedic statement, that is accepted as most authoritative. Therefore Muṇḍaka Upaniṣad and Śvetāśvatara Upaniṣad, they are Vedas. There is statement that two birds are sitting on the same tree. The tree is compared . . . the body is compared with the tree. And two birds, namely the Supersoul, Kṛṣṇa, and the living entity, individual soul, they are sitting together. And one is eating the fruit of the tree and the other is simply witnessing. This is our position.
The other friendly bird, Kṛṣṇa, or Supersoul, is giving us opportunity to act with this body as I like. He's giving us opportunity. Kṣetra-jña. I am the proprietor of this body. I have been allowed to utilize this body as I like. And the facility is given by the Supersoul. So if I like, I can utilize this body for higher grade of life. Kṛṣṇa will give us all facilities. And if I like, I can utilize this body for lower grade of life. Kṛṣṇa will give us facilities.
So He's always friendly. And He gives us also friendly advice that, "Don't act independently. Just act in Kṛṣṇa consciousness under Me. Then you'll be happy." That is His actual instruction. But the living entity does not care for the instruction of the Supersoul. He wants to act independently, and he has to suffer the consequence.
