Sundarī, Bharat ji (Bharat Chakravarti) ki behen hoti hain. Dono Bhagwan Rishabhdev (Adinath) ke santan hain—Bharat aur Bahubali unke putra, aur Brāhmī aur Sundarī unki putriyan. Paramparā ke anusār Brāhmī ne lipi-vidyā ko prachalit kiya aur Sundarī ne ganit aur anek kalāon ki śikṣā ko lok mein फैलाया.
