Some of them are yogīs. They try to acquire some spiritual power to make a show how he can play wonder. A yogī can become very small. If you put him in a room, he will come out. You lock it, he will come out. If there is little space, he will come out. That is called aṇimā. He can fly in the sky, float in the sky. That is called laghimā. In this way, if somebody can show this magic, then immediately he is accepted as very wonderful man. So yogīs, they . . . the modern yogīs, they simply show some gymnastic, but they have no power. So I am not speaking of these third-class yogīs. Real yogī means he has got some power. That is material power.
So yogīs also want this power. And jñānīs also want salvation from the unnecessary working like ass, the karmī. And karmīs want material profit. So they want, everyone. But the bhaktas, devotees, they don't want anything. They want to serve God out of love. Just like a mother loves her child. There is no question of profit. Out of affection, she loves. So when you come to that stage, to love God, that is perfection. So these different processes, karmī, jñānī, yogī and bhakta, out of these four processes, if you want to know God, then you have to accept this bhakti. That is stated in the Bhagavad-gītā, bhaktyā mām abhijānāti (BG 18.55): "Simply through the process of bhakti one can understand Me, God." He never says by other processes. No. Only through bhakti. So if you are interested to know God and love Him, then you have to accept this devotional process. No other process will help you.
