Thus, O Yudhishthira, the histories of the past, the origin of the great Rishis, the holy rivers, the planets and stars and asterisms, the duties of the four modes of life, the four kinds of Homa, the characteristics of the four castes and the four branches of learning were all described in that work (of Brahma).
आगमश्च पुराणानां महर्षीणां च सम्भवः। तीर्थवंशश्च वंशश्च नक्षत्राणां युधिष्ठिर॥ सकलं चातुराश्रम्यं चातुर्होत्रं तथैव च। चातुर्वण्र्यं तथैवात्र चातुर्विद्यं च कीर्तितम्॥
