One thing is pāpa-yoni. So there is no restriction that pāpa-yoni shall remain always pāpa-yoni. Why? They should be given enlightenment. That is Brāhmin-ism. Brāhmin means liberal, and just the opposite word of Brāhmin is kṛpaṇa, miser. A Brāhmin should give chance to everyone, even to the pāpa-yoni, how to become Brāhmin. That is real Brāhmin. And the rascal who thinks that, "I shall remain simply Brāhmin; others shall remain mlecchas and yavanas," he is not Brāhmin; he is Śūdra, because his mind is so crippled. He does not want to see others to become Brāhmin. He is miser, kṛpaṇa. Kṛpaṇaḥ phala-hetavaḥ (BG 2.49).
So our this movement is not for the kṛpaṇas. It is meant for the Brāhmins. We want to become ourself Brāhmin, and we want to make others also Brāhmin, because there is need of Brāhmin at the present moment. The whole human society is now running by the Śūdras, all Śūdras. Kalau śūdra-sambhavaḥ. In this Kali-yuga, everyone is a Śūdra. Maybe born of a Brāhmin family, but because he has no culture . . . the first culture is garbhādhāna-saṁskāra.
If garbhādhāna-saṁskāra is not observed even in a Brāhmin family, he becomes immediately Śūdra. This is the statement of the śāstra. So nobody is observing garbhādhāna-saṁskāra. Therefore, according to śāstra, everyone is a Śūdra. Now because everyone is Śūdra, therefore he cannot be trained up as Brāhmin? No. He can be trained up. Caṇḍālo 'pi dvija-śreṣṭho hari-bhakti-parāyaṇaḥ. If that Śūdra or caṇḍāla can be turned into a devotee of Kṛṣṇa, hari-bhakti-parāyaṇaḥ, then under training he can become better than Brāhmin.
