So we vibrate, and Kṛṣṇa helps from within. Kṛṣṇa said, Sūta Gosvāmī said, śṛṇvatām... Those who are giving, who are taking the chance of hearing Hare Kṛṣṇa mantra... śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ [SB 1.2.17]. Kṛṣṇaḥ is nominative case. Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ. Anything hearing about Kṛṣṇa, that is also pious. Kṛṣṇa is supposed to be doing something according to our material calculation, killing somebody. Or Kṛṣṇa is dancing with other's wife. According to material calculation, this is not allowed. You cannot dance with the other's wife, not in your country, but that is the Vedic civilization. But Kṛṣṇa did it.
Although the gopīs came to dance with Him, captivated by His beauty, but they became purified, puṇya-śravaṇa-kīrtanaḥ. If simply by hearing about Kṛṣṇa one becomes pious, how they become pious simply by dancing with Kṛṣṇa? This is the theory. Not that Kṛṣṇa wanted some young girls to dance with Him. He can create millions of young girls, immediately. But they're devotees. They wanted to dance with Kṛṣṇa, might be captivated by His beauty. But they wanted Kṛṣṇa. Kṛṣṇa gave them chance, "All right, come on. Dance with Me. And be purified." Just try to understand. Just simply by hearing about Kṛṣṇa, one becomes purified, and what to speak of persons who are dancing with Kṛṣṇa. This opportunity is there. You can dance with Kṛṣṇa, you can play with Kṛṣṇa, you can talk with Kṛṣṇa.
