Prabhupāda: To improve our condition there are different processes. One is called karma. Just like generally people are trying to elevate his position, economic condition, working day and night very hard. Similarly, we can also work very hard for our future happiness. We can promote ourself in the heavenly planets and we can degrade ourself to the hellish planets also—both ways. Because as soon as we are engaged in karma, unknowingly or knowingly we commit some sinful activities. This is the position. Just like even if I do not like to kill any animal, still, while walking we are killing many animals, many ants on the street, unwillingly. So that is also taken into account. You cannot kill even an ant. So the karma, karma-kāṇḍa, is not very safe. Even if we want to act very piously, the danger is not over. There are many instances. There was one king. He was very charitable and he was giving cows, many cows to the brāhmaṇas, and . . . you will find this story in the Kṛṣṇa book. So there was some mistake. One brāhmaṇa was taking another brāhmaṇa's cows, and both of them fought and they persisted. The owner wanted, "I want this cow returned back." And the king offered that "Instead of this cow you take ten cows from me. You settle up." No, he would not do that. In this way there was some misunderstanding, and the brāhmaṇa cursed him, as a result of which he had to become an . . . what is called?
Devotees: Lizard.
Prabhupāda: Lizard. Just see this karma-kāṇḍa. He had to become a lizard, that Kṛṣṇa delivered him. So this is karma-kāṇḍa. If there is little discrepancy, then there is great risk. Then jñāna-kāṇḍa. Jñāna-kāṇḍa means to understand things very properly. So jñāna-kāṇḍa is simply speculation, because there is no knowledge of the Supreme Personality of Godhead. So that is also risky. So only bhakti-mārga is not risky.
