Pradyumna: The yoga systems in the Bhagavad-gītā, karma and jñāna... Karma turns into karma-yoga, jñāna system is jñāna-yoga with bhakti and they can't be...
Prabhupāda: Yes, when you add this word yoga, that means bhakti. Yoga means bhakti. Somebody is addicted to these material activities. So they are advised to act in the terms of karma-yoga. What is that karma-yoga? The karma-yoga, if somebody is describing the Bhagavad-gītā, yat karoṣi. "Whatever you are doing, kuruṣva tad mad-arpaṇam. You are working? All right. What you have earned?" "One thousand dollars." "Give Me." Are you prepared? Kṛṣṇa is asking, kuruṣva tad mad-arpaṇam. So if anyone is agreed, "Yes, Kṛṣṇa, here is the money for You," then he's a karma-yogī. Otherwise he's a karmī. And the difference between karma-yogī and karmī means he has to suffer the result, good or bad, and karma-yogī has nothing to suffer because he's doing everything for Kṛṣṇa. Just like Arjuna. In the beginning he considered that "If I kill my kinsmen and my grandfather I'll be sinful." Yes. But the same thing he acted under the direction of Kṛṣṇa. Kṛṣṇa wanted. So he's free. So karma-yogī means he is free from the reaction of activities. He is karma-yogī. Similarly jñāna-yogī. Somebody is addicted to work very hard. Somebody is addicted to speculate philosophically. So for the speculator, Kṛṣṇa says, bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19). The persons who are addicted to speculative knowledge, after many, many births, he comes to the understanding: vāsudevaḥ sarvam iti (BG 7.19), "Vāsudeva, Kṛṣṇa, is everything." That means termination of knowledge. That is jñāna-yoga. If by his research work he tries to understand what is Kṛṣṇa by philosophy or by science or anything, by chemistry, by physics... That is recommended in the Śrīmad-Bhāgavatam:
- ataḥ pumbhir dvija-śreṣṭhā
- varṇāśrama-vibhāgaśaḥ
- svanuṣṭhitasya dharmasya
- saṁsiddhir hari-toṣaṇam
- (SB 1.2.13)
Svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam. It doesn't matter in whatever activities you are engaged, but if you want to know whether your engagement is leading to perfection, then this is the test of perfection. What is that test of perfection? Saṁsiddhir hari-toṣaṇam (SB 1.2.13). Whether by your work the Supreme Personality of Godhead is satisfied. Just like Arjuna did. Arjuna, in the beginning, he wanted to satisfy himself by not fighting, and he fought to satisfy Kṛṣṇa. That is perfection. Saṁsiddhir hari-toṣaṇam (SB 1.2.13). Yes.
