Madhvaon Brahma Sūtra 1.3.26

‘ Even after that,’ that is, even after attaining to the state of being gods, etc., by those who were men (before) ; for indeed the eligibility behoves them, as they possess the capacity of refined intellect (exalted faculties of mind)j etc,; lower beings, etc., on the other hand, are not eligible for the study, as they are destitute of such faculties. Even of these latter, such as possess the exalted faculties of mind, etc., are eligible and there is no objection to it. Moreover there is no (express) prohibition (as to their eligibility); for we actually see cases like those of Jâritâri and others (in the Maliabharat, etc ).
