Arihant (Magadhi Prakrit: arihant, Sanskrit: árhat "conqueror"), is a soul who has conquered inner passions such as attachment, anger, pride and greed. Arihant are also called kevalins (omniscient beings) as they possess Kevala Jnana (pure infinite knowledge). An arihant is also called a jina "victor". At the end of their life, arihants destroy all four gathiya karmas and attain moksha (liberation) and become siddhas, liberated souls. The Ṇamōkāra mantra, the fundamental prayer dedicated to Pañca-Parameṣṭhi (five supreme beings), begins with Ṇamō arihantāṇaṁ, "obeisance to the arihants".
Kevalins - omniscient beings - are said to be of two kinds
- Tirthankara kevalī: 24 human spiritual guides who after attaining omniscience teach the path to salvation.
- Sāmānya kevalī: Kevalins who are concerned with their own liberation.
According to Jains, every soul has the potential to become an arihant. A soul which destroys all kashayas or inner enemies like anger, ego, deception, and greed - responsible for the perpetuation of ignorance - becomes an arihant. According to Jain texts, omniscience is attained on the destruction of the deluding, the knowledge-obscuring, the perception-obscuring and the obstructive karmas, in the order mentioned. The arihants are said to be free from the following eighteen imperfections:
- janma – (re)birth;
- jarā – old-age;
- triśā – thirst;
- kśudhā – hunger;
- vismaya – astonishment;
- arati – displeasure;
- kheda – regret;
- roga – sickness;
- śoka – grief;
- mada – pride;
- moha – delusion;
- bhaya – fear;
- nidrā – sleep;
- cintā – anxiety;
- sveda – perspiration;
- rāga – attachment;
- dveśa – aversion; and
- maraņa – death.
In Jainism, omniscience is said to be the infinite, all-embracing knowledge that reflects, as it were in a mirror, all substances and their infinite modes, extending through the past, the present and the future. According to Jain texts, omniscience is the natural attribute of the pure souls. The self-attaining omniscience becomes a kevalin.
The four infinitudes (ananta cātuṣṭaya) are:
- ananta jñāna, infinite knowledge
- ananta darśana, perfect perception due to the destruction of all darśanāvaraṇīya karmas
- ananta sukha, infinite bliss
- ananta vīrya – infinite energy
Those Arihants who re-establish the 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).
Jain texts mention forty-six attributes of arihants or tirthankaras. These attributes comprise four infinitudes (ananta chatushtaya), thirty-four miraculous happenings (atiśaya), and eight splendours (prātihārya).
The eight splendours (prātihārya) are:
- aśokavrikśa – the Ashoka tree;
- siṃhāsana– bejeweled throne;
- chatra – three-tier canopy;
- bhāmadal – halo of unmatched luminance;
- divya dhvani – divine voice of the Lord without lip movement;
- puśpavarśā – shower of fragrant flowers;
- camara – waving of sixty-four majestic hand-fans; and
- dundubhi – dulcet sound of kettle-drums and other musical instruments.
At the time of nirvana (final release), the arihant sheds off the remaining four aghati karmas:
- Nama (physical structure forming) Karma
- Gotra (status forming) Karma,
- Vedniya (pain and pleasure causing) Karma,
- Ayushya (life span determining) Karma.
These four karmas do not affect the true nature of the soul and are therefore called aghati karmas. After attaining salvation from these arihants become siddhas.
In the Ṇamōkāra mantra, Namo Arihantanam, Namo Siddhanam, Jains worship the arihants first and then to the siddhas, even though the latter are perfected souls who have destroyed all karmas and are considered to be at a higher spiritual stage than arihants. Since siddhas have attained ultimate liberation, they are not accessible. However arihants are accessible for spiritual guidance to human society until their nirvana. 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 (Arhat) should be meditated on.— Dravyasaṃgraha (50)
