Arihant (Jainism)

Arihant (Magadhi Prakrit: अरिहन्त arihant, Sanskrit: अर्हत árhat "conqueror"), is a soul who has conquered inner passions such as attachment, anger, pride and greed.

The four infinitudes (ananta chatushtaya) are:

Those Arihants who re-establish Jain faith are called Tirthankaras. Tirthankaras revitalize the sangha, the fourfold order consisting of male saints (sādhus), female saints (sādhvis), male householders (śrāvaka) and female householders (Śrāvika).
