Puṣṭa Kṛṣṇa: How can we prove that the personality . . .
Prabhupāda: This is the proof. Consciousness developed and the symptoms are there. Just like we are studying this. Our consciousness is developed. This discussion is not possible by the animals, although it has got the all life symptom. Therefore because our consciousness is developed, we can inquire. Therefore in the human form of life it is the only business to inquire about the Absolute. Now, athāto brahma jijñāsā. The animals, they can inquire where is some food, where is some stool. That much. They have no other power. But when one becomes . . . gets this machine of human form of body . . . the Vedānta axiom is, "Now it is the time for inquiring about the Absolute Truth." Athāto brahma jijñāsā. That is real human life, when he inquires about the Absolute Truth. Otherwise, it is animal life. And there are so many department of education, means inquiries. In the human society, there are departmental education: physics department, chemist department, mathematics department, this department, that . . . why? Because there are different inquiries. So Vedānta-sūtra says that the prime inquiry is to inquire about the Absolute Truth. That is human life. If there is no inquiry about the Absolute Truth, then still he is animal. So those who are simply satisfied with the physics and chemistry, they are still animals. They are not human beings. This is the challenge. Still they have not developed the consciousness. And that inquiry, when it is for Kṛṣṇa, that is the final development. And when he understands Kṛṣṇa, his life is perfect. Then he goes back again to the spiritual world. He's quite fit to live there.
