Śrīmad-Bhāgavatam · Text 3.29.31
Who is speaking and story frame
ततो वर्णाश्च चत्वारस्तेषां ब्राह्मण उत्तम: ।
ब्राह्मणेष्वपि वेदज्ञो ह्यर्थज्ञोऽभ्यधिकस्तत: ॥ ३१ ॥
tato varṇāś ca catvāras
teṣāṁ brāhmaṇa uttamaḥ
brāhmaṇeṣv api veda-jño
hy artha-jño ’bhyadhikas tataḥ
Among human beings, the society which is divided according to quality and work is best, and in that society, the intelligent men, who are designated as brāhmaṇas, are best. Among the brāhmaṇas, one who has studied the Vedas is the best, and among the brāhmaṇas who have studied the Vedas, one who knows the actual purport of Veda is the best.
