This movement means we are training our disciples how to make progress towards permanent life. And the material world means they are making progress towards nonpermanent life. So those who are intelligent, they are not interested in nonpermanent life. And those who are foolish, mūḍha, they are interested in this temporary life, and they do not know what is there after death, neither they have got any knowledge what is spirit, what is matter. Ignorance. In darkness.
Therefore one is recommended to associate with sat. Satāṁ prasaṅgān mama vīrya-saṁvido bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ (SB 3.25.25). Satāṁ prasaṅgān. In the association of devotees the discussion on the matter of the Absolute Truth becomes very palatable. We have to hear about the Absolute Truth through the association of persons who are endeavoring to make progress towards eternal life, sat-patham. Yogasya lakṣaṇam. What are the symptoms of yoga? Kapiladeva, Kapiladeva is son of Devahūti. Devahūti is the mother of Kapiladeva. The mother is taking instruction from son. So it doesn't matter. One should not think, "Oh, he is my son. What instruction I shall take from him? I know better than him." No. Son or anyone, anyone, if he knows the science of Kṛṣṇa, he becomes guru. This is the Vedic system. It doesn't matter. Caitanya Mahāprabhu approved this. Caitanya Mahāprabhu was born in a very respectable brāhmaṇa family. He was very advanced learned scholar, and after all He took sannyāsa. So when He was discussing with Rāmānanda Rāya . . . Rāmānanda Rāya was a gṛhastha, householder, and governor of Madras, means politician. A householder, politician, and he was born not in brāhmaṇa family; in kāraṇa, kāyastha family. They are considered as śūdras. So he had no position to instruct Caitanya Mahāprabhu. But Caitanya Mahāprabhu gave him the place of instructor, and He took the position of a listener. Just see Caitanya Mahāprabhu's pastimes. He gave him the position of instructor, and He took the position of student, listener.
