Āchārya (Ācārya) means the Head of an order of ascetics. Some of the famous achāryas are Bhadrabahu, Kundakunda, Samantabhadra, Umaswami.
In Digambara Jainism, Āchārya has thirty-six primary attributes (mūla guņa) consisting in:
According to Jain text, Dravyasamgraha,
Those who themselves practise the five-fold observances in regard to faith (darśanācāra), knowledge (jñānācāra), power (vīryācāra), conduct (cāritrācāra), and austerities (tapācāra), and guide disciples to follow these observances, are the Chief Preceptors (Ācāryas), worthy of meditation.” (52)
Twelve kinds of austerities (tapas)
The external austerities (bāhya tapas) are fasting (anaśana), reduced diet (avamaudarya), special restrictions for begging food (vrttiparisamkhyāna), giving up stimulating and delicious dishes (rasaparityāga), lonely habitation (viviktaśayyāsana), and mortification of the body (kāyakleśa).
Expiation (prāyaścitta), reverence (vinaya), service (vaiyāvrttya), study (svādhyāya), renunciation (vyutsarga), and meditation (dhyāna) are the internal austerities (antarañg tapas).
Acharya Pujyapada's Sarvārthasiddhi:
How are these internal? These are internal as the mind is restrained or subdued in these cases. The removal of sins committed by negligence or under the influence of passions is expiation. Reverence to the holy personages is ‘vinaya’. Service is the help rendered to the saints in difficulty by bodily activity or with things. Contemplation of knowledge or giving up sloth or idleness is study. The giving up of the attitude of ‘I’ and ‘mine’ is renunciation. Checking the ramblings of the mind is meditation.
Five kinds of observances
Five kinds of observances in regard to faith, knowledge, conduct, austerities, and power. These are:
- Darśanācāra- Believing that the pure Self is the only object belonging to the self and all other objects, including the karmic matter (dravya karma and no-karma) are alien; further, believing in the six substances (dravyas), seven Realities (tattvas) and veneration of Jina, Teachers, and the Scripture, is the observance in regard to faith (darśanā).
- Jñānācāra- Reckoning that the pure Self has no delusion, is distinct from attachment and aversion, knowledge itself, and sticking to this notion always is the observance in regard to knowledge (jñānā).
- Cāritrācāra- Being free from attachment etc. is right conduct which gets obstructed by passions. In view of this, getting always engrossed in the pure Self, free from all corrupting dispositions, is the observance in regard to conduct (cāritrā).
- Tapācāra- Performance of different kinds of austerities is essential to spiritual advancement. Performance of penances with due control of senses and desires constitutes the observance in regard to austerities (tapā).
- Vīryācāra- Carrying out the above mentioned four observances with full vigour and intensity, without digression and concealment of true strength, constitutes the observance in regard to power (vīryā).
Six essential duties
Six essential duties (Şadāvaśyaka) of the Ācārya are:
- samatā (sāmāyika) – Equanimity; the state of being without inclination or aversion towards birth or death, gain or loss, glee or pain, friend or foe, etc.
- vandanā – Adoration, salutation; of particular Tīrthañkara, or Supreme Being (Parameşthī).

- pratikramaņa – Self-censure, repentance; to drive oneself away from the multitude of karmas, virtuous or wicked, done in the past.
- kāyotsarga – Non-attachment to the body; contemplating on the pure Self, thereby disregarding the body.
- svādhyāya – Contemplation of knowledge; study of the Scripture, teaching, questioning, reflection, reciting, and preaching.
