We are now interested with nonpermanent goal of life. People are thinking, "If I get a nice car, a nice apartment, a nice wife, a nice bank balance, then I will be happy." But this is asat, because none of this will stay. The bank balance also will not stay, the wife also will not stay, and good position, that will not stay. As soon as the body is finished, everything is finished. Therefore they are called asat. Narottama dāsa Ṭhākura has sung, sat-saṅga chāḍi'kainu asate vilāsa, te-kāraṇe lāgila mor karma-bandha-phāṅsa. Sat-saṅga. Sat-saṅga means persons who are making progress towards the permanent life. They are called sat. Just like this Kṛṣṇa consciousness movement. 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.
