|"Kṛṣṇa consciousness is not so easy. Out of millions and millions of persons, one becomes perfect. And out of millions of perfect, one may understand Kṛṣṇa. That is the version of Kṛṣṇa. So Kṛṣṇa consciousness is not so easy that everyone, each one will become Kṛṣṇa consciousness. It is very difficult. But by the grace of Caitanya Mahāprabhu, by this Hare Kṛṣṇa mantra, this is helping. Otherwise, it is very difficult task. Very difficult. It is recommended in the śāstra, kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet (SB 12.3.51). Simply the Kali-yuga, kaler doṣa-nidhe rājann asti hy eko mahān guṇaḥ (SB 12.3.51). This is the version of Śukadeva Gosvāmī. He described the faulty ocean of this Kali-yuga, and at last he encouraged that "Mahārāja, there is one opportunity in this age." Kaler doṣa-nidhe rājann asti hy eko mahān guṇaḥ, very great opportunity. What is that? Kīrtanād eva kṛṣṇasya: simply by chanting Hare Kṛṣṇa mantra, mukta-saṅgaḥ paraṁ vrajet, he becomes liberated and he goes back to home. This opportunity we are preaching. That's all. "
