In Jainism, a Tīrthaṅkara (Sanskrit: तीर्थंकर "ford-Maker", Tamil: கடவுள் Kaṭavuḷ) is a human being who in addition to achieving liberation and enlightenment as an "Arihant" by destroying all of their soul constraining (ghati) karmas, became a role-model and leader for those seeking spiritual guidance. Tirthankaras revitalize Jain Society by organisation of fourfold Jain Order consisting of monks, nuns, laymen and laywomen. Not all Arihants can become Tīrthaṅkaras. There are 24 Tīrthaṅkaras in this time era and each of them revitalized the Jain Order.
Tirthankara is also said to mean “full moon,” a metaphorical reference to Keval Gnan, (see Kevala Jnana), the spiritual state achieved by exalted and rare beings. Keval Gnan is a state of permanent, perpetual, absolute knowledge of the Soul; it is the precursor to moksha, final liberation from samsara, the cycle of birth and death.
Tīrthaṅkaras religious teaching form the basis for Jain canons. The inner knowledge of all Tīrthaṅkaras is perfect and identical in every respect and their teachings do not contradict one another. However, the degree of elaboration varies according to the spiritual advancement and purity of the society during their period of leadership. The higher the spiritual advancement and purity of mind of the society, the lower the elaboration required.
