So we are ānandamaya. Our nature is to remain always jubilant in pleasure. But because we are in this material contact, we are not jubilant. This is our problem. That Kṛṣṇa is suggesting here, how to solve your problem. He says, vīta-rāga. "Give up this attachment, sense attachment." Rāga. Rāga means attachment. Vīta-rāga-bhaya.
And here we have got one quality, that fear, always fearing. Just like we are having these railings, why? We are afraid, we may not be attacked. The material life means āhāra-nidrā-bhaya-maithunaṁ ca. We must eat, we must sleep, and we must be afraid of, and we must have sex. This is material life. Āhāra-nidrā-bhaya-maithunam. And spiritual life means minus this. No more fear, no more attachment, no more sex life.
Just like in the life of the Gosvāmīs. Nidrāhāra-vihārakādi-vijitau **. Conquered. Conquered over these things, material necessities. So this is called penance. Here it is said. Bahavo jñāna-tapasā. First of all jñāna, understanding our position. This is called jñāna. And then practice tapasya. Tapasya means make these things, material necessities, zero. That is called tapasya. Tapasya. Because we are accustomed to all these things, eating, sleeping, mating and fearing. So to give up it is not possible all of a sudden. That is not possible. Because we are accustomed.
Just like the fan is rotating. You stop the switch, it will rotate. At least, for some time. Because the force is there. Similarly, even if we accept that these things should be stopped—no more eating, no more sleeping, no more sex, no more fearing, that should be... There must be determination. But it may go around because we are practiced to this. Therefore Kṛṣṇa says in the Bhagavad-gītā, api cet su-durācāro bhajate mām ananya-bhāk sādhur eva sa mantavyaḥ (BG 9.30). If we take to Kṛṣṇa consciousness full, even due to our past habits, we are attached to all things, Kṛṣṇa says it doesn't matter. But you keep yourself always in Kṛṣṇa consciousness.
