In the beginning, because we do not know, we may commit offenses. But by chanting, chanting, as we become purified, we must have our aim to become offenseless. Nāma-aparādha. Nāma-aparādha. In the beginning we should not give up chanting, even there is offenses, because by chanting, chanting, we shall be purified. So if one is able to chant Hare Kṛṣṇa mantra without any offenses, he becomes immediately liberated. This is the result. He is mukta-puruṣa, liberated person. He is chanting Hare Kṛṣṇa mantra without any offense. And when pure chanting will be there, then he awakens his original dormant love of Kṛṣṇa. This is the result. In this way.
Another offense is to explain the glories of Hare Kṛṣṇa mantra to a person who is not interested. That is also offense. One who is not interested, if I glorify, "You chant like this; you’ll be this, this . . ." Of course, sometimes we have to do that, but that is forbidden. Because he has no respect for Hare Kṛṣṇa mantra, so there is no need. We have to chant ourself offenselessly, and if somebody hears my offenseless chanting, it will gradually be effective for the persons who are hearing. Śravaṇaṁ kīrtanaṁ (SB 7.5.23). The process is one should chant and one should hear. That we follow. Somebody leads by chanting, and others follow. So if the chanter is pure, then the chanting will be effective. If the chanter is impure, then it will not be effective. But still we should go on.
