[1] Arihants are also called kevalins (omniscient beings) as they possess kevala jnana (pure infinite knowledge).
The Ṇamōkāra mantra, the fundamental prayer dedicated to Pañca-Parameṣṭhi (five supreme beings), begins with Ṇamō arihantāṇaṁ, "obeisance to the arihants".
A soul which destroys all kashayas or inner enemies like anger, ego, deception, and greed, responsible for the perpetuation of ignorance, becomes an arihant.
[1] According to Jain texts, omniscience is attained on the destruction of four types of karmas– deluding, the knowledge-obscuring, the perception-obscuring and the obstructive karmas, in the order mentioned.
These attributes comprise four infinitudes (ananta chatushtaya), thirty-four miraculous happenings (atiśaya), and eight splendours (prātihārya).
The Dravyasaṃgraha, a major Jain text, states: Having destroyed the four inimical varieties of karmas (ghātiyā karmas), possessed of infinite faith, happiness, knowledge and power, and housed in most auspicious body (paramaudārika śarīra), that pure soul of the World Teacher (Arihant) should be meditated on.
