त्रीणि कर्माणि जानीत ब्राह्मणानां तु जीविका । याजनाध्यापने चोभे शुद्धाच्चापि प्रतिग्रह:,इनमेंसे तीन कर्म--याजन (यज्ञ कराना), अध्यापन (पढ़ाना) और श्रेष्ठ पुरुषोंसे दान लेना--ये ब्राह्मणकी जीविकाके साधन हैं
trīṇi karmāṇi jānīta brāhmaṇānāṃ tu jīvikā | yājanādhyāpane cobhe śuddāccāpi pratigrahaḥ ||
Vāyu said: “Know that there are three rightful means of livelihood for Brahmins: officiating at sacrifices for others, teaching sacred learning, and accepting pure gifts (given in a righteous manner).”
वायुदेव उवाच
A Brahmin’s livelihood should rest on dharmic functions—serving society through priestly officiation and teaching—and on receiving only ‘pure’ gifts, i.e., offerings obtained and given righteously, without compromising integrity.
Vāyu is instructing about proper conduct (dharma), specifically defining the legitimate means of subsistence for Brahmins and emphasizing ethical constraints on accepting gifts.
