how one can become trithankar

In Jain philosophy, a Tīrthaṅkara is a supreme spiritual teacher who has conquered all karmic bonds and attained Kevala Jñāna (omniscience). To become a Tīrthaṅkara, an individual must undergo intense spiritual purification through right faith, right knowledge, and right conduct, ultimately achieving liberation from all Ghātiyā (destructive) karmas. Upon attaining omniscience, the Tīrthaṅkara establishes the fourfold community (caturvidha sangha) comprising monks, nuns, laymen, and laywomen, thereby re-establishing the Jain doctrine (Dharma) in the world. This process is cyclical and occurs in every half time cycle (Avasarpini and Utsarpini), with exactly 24 Tīrthaṅkaras appearing in each half cycle. The Tīrthaṅkara's role is pivotal as they provide the path for liberation through their teachings and exemplary conduct. The attainment of Tīrthaṅkara status is thus the culmination of spiritual evolution marked by the removal of all Jñānāvaraṇīya (knowledge-obscuring) karmas and the establishment of Jainism anew.
