Revatīnandana: Verse 25: "One who is beyond duality and doubt, whose mind is engaged within, who is always busy working for the welfare of all sentient beings and who is free from all sins achieves liberation in the Supreme."
Prabhupāda: Now, these things are very important things, "whose mind is engaged within, who is always busy working for the welfare of all sentient beings." This chanting of Hare Kṛṣṇa, it is welfare work for all sentient beings, even the worms, the microbes, the cockroaches. So many living entities are within this room. By hearing this vibration of Hare Kṛṣṇa mantra they will be getting also the result.
That is described in Caitanya-caritāmṛta. When Lord Caitanya questioned Haridāsa Ṭhākura about the efficacy of chanting, how he described? You will find it in the Teachings of Lord Caitanya. It is a fact. If you are chanting within this room, and if you find nobody is coming to participate in the kīrtana, don't be disappointed. There are many germs, worms, cockroaches within this room—they are being benefited. They are being benefited. You cannot find any place without any living entities. You just find out one hole, you will see hundreds of ants are coming out.
So living entities are in the air, in the water, in the holes—everywhere. And this vibration . . . everyone, every living entity, has got this ear. So this sound is so powerful because it is spiritual that it will act even on the ants and the trees and the birds and the bees, what to speak of human being. It is so nice thing.
So those who are chanting . . ."One who is always busy working." What is the business of these Kṛṣṇa conscious students? They are busy in chanting Hare Kṛṣṇa, in distributing knowledge in Kṛṣṇa consciousness. Therefore they are doing the best welfare work in the world. Other welfare work will be finished as soon as this body is finished. But these welfare activities will not be finished. If one hears one day, one minute, one second this vibration of chanting, it will act someday. Therefore this is the best welfare activity in the human society.
"And who is free from all sins achieves liberation in the Supreme." So it is said that:
- eka kṛṣṇa-nāme yata pāpa hare,
- pāpī haya tata pāpa karibare nare
- (Prema-vivarta).
The Kṛṣṇa name is so powerful transcendentally, spiritually, that if you chant once "Kṛṣṇa," all your sinful activities, reaction, are immediately finished. One may say that, "He was not so sinful. He was little sinful; therefore it is finished." But this verse says that the vibration of "Kṛṣṇa," this sound, has so much potency that it can finish the reaction of all sinful activities as you cannot perform in your various lives. Even if you are very expert in committing sinful activities, still, this will finish, provided it is chanted offenselessly. It has got the power.
So if we always chant . . . suppose I am now freed from all sinful reaction. I may be attacked again. That is quite possible. I may be free from the disease but I may be attacked again by this disease. That is possible. But if you always keep yourself constantly in Kṛṣṇa consciousness, chanting Hare Kṛṣṇa—therefore we supply the beads and ask the student, "Chant Hare Kṛṣṇa"—then sinful activities cannot touch you. These are the processes. And if you keep yourself without being touched by the sinful activities, then one who does so achieves liberation in the Supreme. Then your liberation is guaranteed.
