You can find out rascal mahātmā, simply by changing dress, without Kṛṣṇa consciousness, declaring himself as God or Kṛṣṇa. Kick on their face. Kṛṣṇa is different from all these rascals. But if you understand Kṛṣṇa, if you are so fortunate—ei rūpe brahmāṇḍa bhramite kona bhāgyavān jīva (CC Madhya 19.151). Only the most fortunate persons can understand Kṛṣṇa, what is Kṛṣṇa. Ei rūpe.
There are many, many millions and trillions of living entities within this universe. And they are rotating in different species of life, 8,400,000—in this way, unfortunate. Simply repetition, birth and death, birth and death in different... Out of them, if one is the greatest fortunate, he is given the chance, guru-kṛṣṇa-prasāde pāya bhakti-latā-bīja. By the mercy of guru and Kṛṣṇa, he gets the seed of devotional service. And if he's intelligent, unless he is intelligent, otherwise how he gets the seed? That is initiation. And if he waters... Just like if you get a nice seed, you have to sow it and pour little, little water... Then it will grow. Similarly, anyone who by great fortune has come into Kṛṣṇa consciousness, the seed of devotional service, he should water it. And what is the water? Śravaṇa-kīrtana-jale karaye secana (CC Madhya 19.152). This is watering. This hearing and chanting about Kṛṣṇa. This is watering. Don't be absent from the class. This hearing and chanting is watering the seed of devotional service. If you make it official and be absent from hearing... This is most important thing. Śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23). This is most important thing. To hear. Śravaṇaṁ kīrtanam does not mean hearing and chanting of any other entity. No. Viṣṇu. Śravaṇaṁ kīrtanam. The rascals, they have manufactured "kālī-kīrtana".Where is there in śāstra there is kālī-kīrtana, śiva-kīrtana? No. Kīrtana means glorifying the Supreme Lord, Kṛṣṇa. That is kīrtana. Not any other kīrtana. But they have manu... competition, kālī-kīrtana. Where is in the śāstra kālī-kīrtana? Durgā-kīrtana? These are all nonsense. Simply Kṛṣṇa. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam (SB 7.5.23). Kṛṣṇa should be worshiped, Kṛṣṇa should be heard, Kṛṣṇa should be chanted, Kṛṣṇa should be remembered. In this way, you'll advance Kṛṣṇa consciousness.
