Relics found from Harrapan excavations like seals depicting Kayotsarga posture, idols in Padmasana and a nude bust of red limestone give insight about the antiquity of the Digambara tradition.
According to Digambara texts, after liberation of the Lord Mahavira, three Anubaddha Kevalīs attained Kevalajñāna (omniscience) sequentially - Gautama Gaņadhara, Acharya Sudharma, and Jambusvami in next 62 years.
