For the interest of human beings, it is necessary for a bodhisatta to study extensively and to be well informed. Buddhism requires bodhisatta aspirants to learn the Five Vidya (S. vijja, meaning knowledge), these are:

⑴ Sabda-vidya, viz. phonology and philogy;

⑵ Silpakarma-vidya, viz. all technology, techniques, crafts, arithmetic, calendar, etc.;

⑶ Cikitsa-vidya, viz. medical science and pharmacology;

⑷ Hetu-vidya, viz. logic;

⑸ Adhyatma-vidya, viz. Buddhist studies.

The five vidyas must be mastered by scholars. “To be broadly erudite, and sincerely compassionate” is the requirement for bodhisattahood. Mahayana Buddhism particularly calls for learning whatever is difficult to learn, and all that should be learned. (From Essentials of Buddhism: Questions and Answers)
