Generally yoga is understood as meditation. But yoga, real meaning of yoga— to keep, to keep in touch with the Supreme—that is called yoga, to keep in touch. So you have to work for, the er, from the platform of spiritual consciousness. At the same time you have to work. The Lord never says that "You stop work," never says. Arjuna . . . Arjuna's friend was Lord Kṛṣṇa, but Kṛṣṇa never said . . . He is God Himself. He is the Supreme Personality of God Himself. He never said Arjuna that "I am your friend. I shall supply all your necessities. You don't require to work. You stop." No, He never said that. Rather, Arjuna was declining to fight, but Kṛṣṇa is inducing him to fight. So in spiritual platform it is . . . there is no question of stopping work, no question of stopping work. But work for the Supreme. That's all, īśāvāsyam idaṁ sarvam (ISO 1), with God consciousness.
Now, there are three processes of yoga: jñāna-yoga, and karma-yoga, and bhakti-yoga. Now, jñāna-yoga, take for example jñāna-yoga. Jñāna-yoga means to keep in touch with the Supreme by speculation of higher knowledge, that discriminating what is spirit and what is matter. So there are philosophers, they are discriminating that, "This is matter . . ." Neti neti, "This is matter, and this is spirit." Now, that requires study, and that requires knowledge also.
