Pradyumna: "The Vedas are my eternal, transcendental sound incarnation. Therefore the Vedas are śabda-brahma. In this world, the brāhmaṇas thoroughly study all the Vedas, and because they assimilate the Vedic conclusions, they are also to be considered the Vedas personified. The brāhmaṇas are situated in the supreme transcendental mode of nature, sattva-guṇa. Because of this they are fixed in mind control, or śama; sense control, dama; and truthfulness, or satya. They describe the Vedas in their original sense, and out of mercy, or anugraha, they preach the purpose of the Vedas to all conditioned souls. They practice penance, or tapasya, and tolerance, titikṣa, and they realize the position of the living entity and the Supreme Lord, anubhavaḥ. These are the eight qualifications of the brāhmaṇas. Therefore among all living entities no one is superior to the brāhmaṇas."
Prabhupāda:
- dhṛtā tanūr uśatī me purāṇī
- yeneha sattvaṁ paramaṁ pavitram
- śamo damaḥ satyam anugrahaś ca
- tapas titikṣānubhavaś ca yatra
- (SB 5.5.24)
So the meaning is clearly described in the translation. So the brāhmaṇas, why they are accepted as the supreme in the human society? On account of these qualities. We have discussed this point, that either brāhmaṇa, kṣatriya, vaiśya, especially dvijottama... The brāhmaṇas are called dvijottama. Dvija-śreṣṭhā. Ataḥ pumbhir dvija-śreṣṭhā. Dvija means twice-born, one birth by the father and mother and the other birth by Vedic knowledge and spiritual master. Twice-born. So the daśa-vidhā-saṁskāra, purificatory processes... Saṁskarād bhaved dvijaḥ. Unless one undergoes the purificatory process, he cannot be called twice-born. Janmanā jāyate śūdraḥ: "By birth everyone is a śūdra, fourth-class man." Practically we see that children, they are sent to school. Why they are sent to school? Because by birth he is foolish, abodha-jātaḥ. There is no knowledge. Therefore he should be sent to school, as he makes progress, to colleges, to learn higher, higher. This is the material arrangement.
