So devotional service is not a sentiment. It is most scientific, just to become freed from the contamination of this material world. That means one who is devotee, he is already mukta; he is liberated. That is also stated in the Bhagavad-gītā, that,
- māṁ cāvyabhicāriṇi
- bhakti-yogena yaḥ sevate
- sa guṇān samatītyaitān
- brahma-bhūyāya kalpate
- (BG 14.26)
So if you want to be brahma-līna, so that is . . . Actually brahma-līna means to be engaged twenty-four hours in devotional service. That is brahma-līna. There is not a second vacant without Kṛṣṇa's service. Just like Caitanya Mahāprabhu said, śūnyāyitaṁ jagat sarvaṁ govinda-viraheṇa me: "I am seeing everything vacant without Govinda (CC Antya 20.39)." That is Kṛṣṇa consciousness. He is thinking simply on Kṛṣṇa. And without Kṛṣṇa, everything is zero. So simply to make the material world zero, śūnyavādi . . . Just like the Buddhist philosophers, they think śūnyavādi. And the Māyāvādī, nirviśeṣa. They are practically the same. The Buddhists say, "There is no God." And the Māyāvādīs say, "There is God, but He has no head, tail, nothing." It is in the indirect way to say there is no God. What is difference? If somebody says, "There is no God," and if somebody says, "There is God, but He has no head, He has no tail, He cannot eat, He cannot sleep," negatively—the same definition in a negative way. Therefore Caitanya Mahāprabhu says that veda na māniyā bauddha haila nāstika. Our standard of philosophy, especially Vaiṣṇava philosophy . . . Anyone who does not accept the Vedic principle . . . Because vedaiś ca sarvair aham eva vedyam (BG 15.15). If you do not accept the Vedic authority, then how you can understand God, Kṛṣṇa? That is not possible. So anyone who says, "There is no God. I don't care for the Vedas," he is calculated as nāstika. So Caitanya Mahāprabhu said . . .
The Buddhists, they decry the authority of Vedas . He had to do that. There was no way. Jayadeva Gosvāmī offered his prayer to Lord Buddha: nindasi yajña-vidher ahaha śruti-jātam. Śruti. In the Vedas there is recommendation of yajña, and in some of the yajñas there is recommendation of killing paśu. So Lord Buddha, he preached ahiṁsā paramo dharma, no killing of animals. So these paṇḍitas, they will give evidence that in the Vedas there is description of killing animals. How you can stop it? So therefore he said, "I don't care for your Vedas." Nindasi yajña-vidher ahaha śruti-jātam. Why? Why he did so? Sadaya-hṛdaya-darśita-paśu-ghātam. He was so much compassionate to see unnecessary killing of animals. Sadaya-hṛdaya. Therefore ahiṁsā paramo dharmaḥ. That was his . . . Although he is the incarnation of God . . . Keśava dhṛta-buddha-śarīra, jaya jagadīśa hare.
