Tirtha (Jainism) in the context of "Tirthankara"

In Jainism, a Tirthankara (IAST: tīrthaṅkara; lit. 'ford-maker') is a saviour and supreme preacher of the dharma (righteous path). The word tirthankara signifies the founder of a tirtha, a fordable passage across saṃsāra, the sea of interminable birth and death. According to Jains, tirthankaras are the supreme preachers of dharma, who have conquered saṃsāra on their own and made a path for others to follow. After understanding the true nature of the self or soul, the Tīrthaṅkara attains kevala jnana (omniscience). A Tirthankara provides a bridge for others to follow them from saṃsāra to moksha (liberation).

In Jain cosmology, the wheel of time is divided into two halves, Utsarpiṇī, the ascending time cycle, and avasarpiṇī, the descending time cycle (said to be current now). In each half of the cycle, exactly 24 tirthankaras grace this part of the universe. There have been infinitely many tirthankaras in the past. The first tirthankara in the present cycle (Hunda Avsarpini) was Rishabhanatha, who is credited with formulating and organising humans to live in a society harmoniously. The 24th and last tirthankara of the present half-cycle was Mahavira (599 BC–527 BC). History records the existence of Mahavira and his predecessor, Parshvanatha, the 23rd tirthankara.
