If you do not prepare yourself in this life, if you simply become engaged in sinful activities, then you'll be degraded. As you are elevated to the human form of life, if you do not utilize this human form of life, if we behave like animals, then we shall be converted again into animals. People not, I mean to say, afraid of becoming animals. I have asked so many people that, "Suppose if you become animal in the next life?"
He says: "What is the harm?" People have become so degraded that one does not become afraid of becoming animal. They are thinking there is no . . . because their life has been so modeled, it is no better than animal life. So they do not see any difference between animal life and human life. Therefore to become animal or human being, they do not mind. This is the position.
So this question was raised by Arjuna that, "This life is meant for elevating to further, higher standard of life. Why people, they degrade? Why they are degraded?" So Kṛṣṇa, when this question was raised by Arjuna to Kṛṣṇa, and Kṛṣṇa answered:
- kāma eṣa krodha eṣa
- rajo-guṇa-samudbhavaḥ
- (BG 3.37)
"My dear Arjuna, this is due to lust and anger." Kāma eṣa krodha, rajo-guṇa-samudbhavaḥ. This is due to our association with the modes of material nature known as passion.
