«So if we discuss about kṛṣṇa-kathā, the words of Kṛṣṇa… There are two books, words of Kṛṣṇa. One, Bhagavad-gītā. Every Vedic literature is kṛṣṇa-kathā, but these two books especially, kṛṣṇa-kathā. Bhagavad-gītā, Kṛṣṇa is directly speaking, and Śrīmad-Bhāgavatam, directly speaking about Kṛṣṇa. Both of them are kṛṣṇa-kathā. So therefore here it is said that uttama-śloka-vārtayā. Vārtā means message, words. So if we pass our time simply by reading and talking about Kṛṣṇa, then the sun will not be able to take away our life. This is the secret. If you want to become immortal, then you always be engaged in kṛṣṇa-kathā.»
