Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.39 - Los Angeles, May 1, 1973
Therefore if you remain in Kṛṣṇa consciousness, if you always keep Kṛṣṇa within your mind, then... Just like when the sun is there, there cannot be any darkness. Similarly, if you keep kṛṣṇa sūrya, the Kṛṣṇa sun... That is our motto in the Back to Godhead: kṛṣṇa sūrya sama māyā andhakāra. Kṛṣṇa is just like brilliant sunshine, and the māyā, ignorance, is just like darkness. But when or while or where the sun is there, there cannot be any darkness. Similarly, you keep Kṛṣṇa in consciousness always, there cannot be any ignorance; there cannot be any darkness. You'll be walking very freely in bright sunshine of Kṛṣṇa. Don't try to make Kṛṣṇa absent. That is Kuntī's prayer. "My dear Kṛṣṇa, You are going to Dvārakā..." This is an example. They are not going.
Kṛṣṇa is not going from the Pāṇḍavas. Just like in Vṛndāvana. In Vṛndāvana, when Kṛṣṇa left Vṛndāvana for Mathurā... So in the śāstra it is said: vṛndāvanaṁ parityajya padam ekaṁ na gacchati, Kṛṣṇa goes not go even one step from Vṛndāvana. He doesn't go. He's so much attached to Vṛndāvana. Then we see that Kṛṣṇa left Vṛndāvana, went to Mathurā. So how is that, He went so far away? And did not return for many years? No. Kṛṣṇa actually did not leave Vṛndāvana. Because since Kṛṣṇa left Vṛndāvana, all the inhabitants of gopī, they were simply thinking of Kṛṣṇa and crying. That was their business. Mother Yaśodā, Nanda Mahārāja, Rādhārāṇī, all the gopīs, all the cows, all the calves, all the cowherd boys, their only business was to think of Kṛṣṇa and cry. Absence, separation.
