Either you are engaged in the activities of karma or either you are engaged in the activities of speculative knowledge or acquiring knowledge, this is jñāna-kāṇḍa and karma-kāṇda. So Narottama dāsa Ṭhākura says that "Both these, jñāna-kāṇḍa and karma-kāṇḍa, are pots of poison. Either you drink this or that, it doesn't matter." Karma-kāṇḍa—according to karma you'll get a different body. Jñāna-kāṇḍa also. If you actually become very much advanced in knowledge, you can get a body in a brāhmaṇa family, in a very educated family. But I'll have to go through the transmigration of the soul, repetition of birth and death.
