So when I started this movement, somehow or other, I tried to fix up the mind of these boys in Kṛṣṇa. In the beginning I never said that "You have to do this. You have to do that." But somehow or other, they are very nice boys, so they fixed up their mind in Hare Kṛṣṇa chanting. Kṛṣṇa and chanting Hare Kṛṣṇa—the same thing. Therefore we... Our process is to chant, kīrtanīyaḥ sadā hariḥ [Cc. Ādi 17.31], chant Hare Kṛṣṇa always. Then the mind becomes... Chant and hear. Yena tena prakāreṇa. Then everything will be complete.
It is so... As we are fallen at the present moment in this age, the remedy is also very effective. Kīrtanād eva kṛṣṇasya paraṁ vrajet [SB 12.3.51]. Kīrtanād eva kṛṣṇasya nitya-muktaḥ paraṁ vrajet.
This is the special advantage of this Kali-yuga, because people are so fallen that it is very difficult to raise them to the standard of spiritual understanding by the prescribed method. Prescribed method means tapasā brahmacaryeṇa śamena damena niyamena tyāgena [SB 6.1.13]. It is very difficult. Therefore Caitanya Mahāprabhu has given us His blessings, kīrtanīyaḥ sadā hariḥ [Cc. Ādi 17.31].
