चतुर्युगाख्यान (Caturyuga-Ākhyāna) — Yuga-wise Origins and Measurements of Beings
एते मन्त्रकृतश्चैव वैश्यानां प्रवराः स्मृताः / इत्येषा नवतिः प्रोक्ता मन्त्रा यैरृषिभिः कृताः / ब्राह्यणाः क्षत्रिया वैश्या ऋषिपुत्रान्निबोधत
ete mantrakṛtaścaiva vaiśyānāṃ pravarāḥ smṛtāḥ / ityeṣā navatiḥ proktā mantrā yairṛṣibhiḥ kṛtāḥ / brāhyaṇāḥ kṣatriyā vaiśyā ṛṣiputrānnibodhata
These are remembered as the mantrakṛta and the foremost pravaras of the Vaiśyas. Thus it is declared that the mantras composed by the ṛṣis are ninety in number. O Brāhmaṇas, Kṣatriyas, and Vaiśyas, know the sons of the ṛṣis by their names.
