varṇadharmās tathākhyātā dharmā ye cāśrameṣu vai
śrotum icchāmy ahaṃ vaṃśāṃs tāṃs tvaṃ prabrūhi me guro //

MAITREYA.--Venerable preceptor, you have explained to me the perpetual and occasional ceremonies which are to be performed by those righteous individuals who are diligent in their devotions; and you have also described to me the duties which devolve upon the several castes, and on the different orders of the human race. I have now to request you will relate to me the dynasties of the kings who have ruled over the earth.
