People suffer out of ignorance. That is called pāpa, sin. Any criminal... Mostly, he does not know the real law. He commits something unknowingly, by ignorance, and he becomes a subject of criminal punishment. Therefore ignorance is sinful life. Ignorance. So people should be enlightened from ignorance. And that is real religion. One should be enlightened himself, and one should enlighten others also. That is the mission of Kṛṣṇa consciousness. This is Lord Caitanya Mahāprabhu's mission. Lord Caitanya Mahāprabhu says, bhārata-bhūmite manuṣya janma haila yāra. Not the cats and dogs, animals. Manuṣya. On the land of Bhāratavarṣa, one who has taken his birth as a human being... This point is very important.
