According to Mahavira, in order to realise truth, one should

According to Mahavira and Jaina doctrine, the cycle of birth and rebirth is shaped by karma, which is created by the union of the soul (jiva) and matter (ajiva) [2]. To realize truth and achieve salvation (Kevala Jnana), one must free the soul from the bondage of karma. This liberation is achieved through rigorous asceticism, penance, and the performance of austerities [2]. Mahavira emphasized that salvation cannot be attained through sacrifices or worshipping deities; instead, it requires enduring physical hardships and renouncing worldly possessions [2]. Monastic existence, involving strict vows and the endurance of bodily pain (tapasya), is considered a necessary condition to 'burn away' accumulated karma and prevent new karma from attaching to the soul [2]. Thus, enduring pain to the body through ascetic practices is the prescribed path to realizing the ultimate truth in Jainism.
