Without being anxiety-less, nobody can understand the science of God. This is the verdict of Bhagavad . . . Śrīmad-Bhāgavatam. Evaṁ prasanna-manaso bhagavad-bhakti. One who has executed the process of bhagavad-bhakti according to the rules and regulations, śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23), he'll be prasanna-manaso. The same thing, as it is confirmed in the Bhagavad-gītā: brahma-bhūtaḥ prasannātmā (BG 18.54). The Bhāgavata says, evaṁ prasanna-manaso bhagavad-bhakti-yogataḥ, bhagavat-tattva-vijñānam (SB 1.2.20). Bhagavat-tattva, the science of God, is a vijñāna. It is a science; it is not sentiment. Sentiment: I close my eyes and shed some tears, and then I go for smoking cigarette. That sentiment will not help us. It is a science. Just like Caitanya Mahāprabhu said: yei kṛṣṇa-tattva-vettā sei guru haya (CC Madhya 8.128). Yei kṛṣṇa-tattva-vettā. One who knows the science of Kṛṣṇa, he can become guru. Pṛthivīṁ sa śiṣyāt. He can make disciples all over the world. Pṛthivīṁ sa śiṣyāt. So Caitanya Mahāprabhu confirmed it:
- kibā vipra kibā śūdra nyāsī kena naya
- yei kṛṣṇa-tattva-vettā sei guru haya
- (CC Madhya 8.128)
It doesn't matter whether one is a gṛhastha or one is a sannyāsī or one is a brahmin or not brahmin. It doesn't matter. Because this is not the science of this physiological ana . . . anatomical science or cobbler's science. Cobbler's science means cobbler knows what kind of skin it is. It is not like that. Neither cobbler's science nor anatomical science or physiological science. Bhagavat-tattva-vijñānam. It is another science.
