Practically see how easy to practice this method of saṅkīrtana, Hare Kṛṣṇa, and how quickly it acts. This is a fact; this is not a story. We have got hundreds of students in different centers—just see their behavior, just see their face, how they are advancing. Therefore this is not a new thing. This is already there—but for this age. Just like in the drug shop the medicinal is already there, but an experienced physician prescribes the particular medicine that, "This is fit for you." Similarly this . . . don't think that this saṅkīrtana movement we have newly introduced. It is in the Purāṇas mentioned. But Caitanya Mahāprabhu, taking consideration of the fallen condition of this age, He has recommended this metho. . . medicine, "It is this for you." Not that it is newly invented. Nothing . . . we don't invent anything. This is called paramparā system. We accept the oldest thing. Don't think that we have manufactured something. For this reason I had many correspondences—you have seen also—with Dr. Staal of the California University. I protested, that, "This is not a new thing." He gave a suggestion that it may be a new thing. No. It is not new; it is the oldest.
So this oldest thing is recommended by Śukadeva Goswāmī. He said kaścit. Mark this word. Kaścit, kaścit means "someone"; not for all. This method, this transcendental method of self-realization by bhakti-yoga, it is not possible to accept by everyone. It is very difficult. In the Bhagavad-gītā Kṛṣṇa, Lord Kṛṣṇa, says, yeṣāṁ anta-gataṁ pāpaṁ (BG 7.28): anyone who has finished the all reactionary result of sinful life, yeṣāṁ anta-gataṁ pāpaṁ. Anta- gataṁ means "gone," "finished." Pāpaṁ—sinful life. Yeṣāṁ anta-gataṁ pāpaṁ, janānāṁ puṇya-karmaṇām. And how one can become completely freed from the contamination of sinful life?
Puṇya-karmaṇām: he has to act piously, counteract. So counteracting, by counteracting with pious activities, when one is completely freed from the resultant action of sinful life, te, such persons, te dvandva-moha- nirmuktā: without any doubt, without any hesitation.
