Short answer: In Jainism, there is a clear distinction between the core spiritual teachings (the Tirthankaras and their moral messages) and the many legendary/folk stories that accumulate around them. A “Vidyadhari lineage” attached to Lord Rishabhanatha is not part of the central canonical biography that most Jains study. If such a lineage is mentioned, it is a later, folkloric addition and not considered a definitive or universally accepted part of Rishabha's true, primary lineage.

Key points to understand:

• Rishabhanatha (Adinath) and his main line are presented in Jain shastra as the progenitor and ancestors who established dharma, with a focus on spiritual teachings, governance, and renunciation. Detailed genealogies and legendary figures beyond the core line are often found in later narratives.
• Vidyadharas or Vidyadhari (celestial or semi-divine beings associated with knowledge and arts) appear in many Indian mythic traditions. In Jain narrative, such beings can appear in stories and puranic-like tales, but their presence does not redefine the essential, historical-teachings focus of a Tirthankara.
• Digambar and Śvetāmbar traditions differ in many details of legends and chronologies. Both traditions preserve the essential dharma but acknowledge that some stories are regional, popular, or didactic in nature rather than definitive doctrinal claims.
• The spiritual aim remains the same: to attain liberation through right faith, right knowledge, and right conduct. Mythic elements are usually illustrative, not doctrinal about the historical person of a Tirthankara.

If you want, I can explain more precisely how Digambar and Śvetāmbar sources narrate Rishabhanatha’s lineage and where folkloric figures like celestial beings appear in their stories.
