In Jainism, a Tirthankara ("Fordmaker") (also Tirthankara or Jina) is a human who achieves enlightenment (perfect knowledge), through asceticism. A Tirthankar becomes a Jina (after totally conquering anger, pride, deceit, desire, etc.). A Tirthankar is the founder of a "Tirth", a Jain community which acts as a "ford" across the "river of human misery".
