So those who are in devotional service, they have got two things: they can see what is māyā and what is Kṛṣṇa. That is perfect life. Then he can understand how this world is going on, how Kṛṣṇa is working. Everything becomes revealed. Bhakti-yoga is so powerful. Otherwise, what qualification we have got in comparison, their M.A., Ph.D., D.S.D. and so on, so on? Still they cannot touch the right point. Just like Dr. Stahl in Berkeley University. He talked with me, and at last he became silent. So we can challenge like that. Just like we are discussing so many philosophers.
So bhakti-yoga is so nice. So you execute bhakti-yoga very nicely, and then you become the topmost learned man in the world. This is a fact.
