So mahātmā's business is: ananyāś cintayanto māṁ ye janāḥ paryupāsate (BG 9.22). A mahātmā has no other business than devotional service, śravaṇaṁ kīrtanaṁ viṣṇoḥ, always hearing about the Supreme Lord, always glorifying the Supreme Lord, śravaṇaṁ kīrtanaṁ viṣṇoḥ. Viṣṇu is the Supreme Personality of Godhead. But that we do not know. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). That we do not know. And because people, they do not know it, therefore this mission, Kṛṣṇa consciousness, is there, just to make people enlightened: "Know it now. Know it now. In the other, previous lives, cats, dogs, trees, and fishes and insects and all so many other—there are eight million, four hundred . . . you could not know it. Now you have got this human form of body, take advantage of this knowledge. Take advantage of the information given in the Vedic literature." Uttiṣṭhata jāgrata prāpya varān nibodhata (Kaṭha Upaniṣad 1.3.14). "You have got so much advantages. Now learn them. And you have got developed consciousness, human being. Try to understand them. And then your life will be successful."
That . . . to come to that state, here it is stated that you have to purify your citta, consciousness, svaccham, crystallike. Crystallike, transparent, svaccham. And that śāntaṁ bhagavataḥ padam, that is the stage of understanding Bhagavān. Evaṁ prasanna-manaso bhagavad-bhakti-yogataḥ (SB 1.2.20). This stage can be attained by bhagavad-bhakti, by devotional service. This devotional service begins simply by hearing and chanting. We have got all these books. Anyone can take advantage of these books. Now it is translated into English. Of course, we are getting very, very good, encouraging report from Western countries. Our books are selling very nicely, beyond our capacity of supply, all over Europe, America especially. Especially in America, all libraries, colleges, professors, educationist, they are very, with great respect, receiving these books.
So these books are there to remind us: ataeva kṛṣṇa veda-purāṇa paḍilā. Because we have forgotten Kṛṣṇa, because we have forgotten God on account of restless mind, so we have to make it śānta, calm and peaceful. Without becoming calm and peaceful, you cannot understand what is God. Ceta etair anāviddhaṁ sthitaṁ sattve prasīdati. When our heart will be no more attacked by the sattva-guṇa and rajo-guṇa, we come into the platform . . . er, rajo-guṇa and tamo-guṇa . . . naṣṭa-prāyeṣu abhadreṣu nityaṁ bhāgavata-sevayā (SB 1.2.18). This class is held for understanding Śrīmad-Bhāgavatam. Why? Just to cleanse the heart.
