brāhmaṇena niṣkāraṇo dharmaḥ ṣaḍaṅgo vedo’dhyeyo jñeya iti |
pradhānaṁ ca ṣaṭsv aṅgeṣu vyākaraṇam |
pradhāne ca kṛto yatnaḥ phalavān bhavati |
(Mahābhāṣya)
“Dharma, the six aṅgas [of the Veda], and the Veda are to be received and learned by a brāhmaṇa without cause [i.e., without any selfish motive, and without questioning the reason why this should be done]. Among the six aṅgas, vyākaraṇa (grammar) is the foremost, and exertion done in regard to that which is foremost becomes fruitful.”
