In Jain tradition, Vishwanandi was a prince in the previous-life story of Lord Mahavira. He was the son of King Vishwabhuti and Queen Jaini, and later he renounced the world and became a Jain monk. ( jainsattva.com)

I could not find a clear Jain reference for “Bhuyasha” with that exact spelling. It may be a spelling variation or a different name. If you meant Vishakhanandi / Vishakhanandi, he is mentioned in the same story as Vishwanandi’s cousin. ( jainsattva.com)
