Here are the main kinds of tapasya (austerity) taught in Jainism, presented simply and clearly:

• External (Bahir-tapasya): physical disciplines and practices

- Fasting (upavasa, vrat): observing fasts for a day, a fraction of a day, or longer periods. - Upavasa-related austerities: eating at specific times, eating minimally, or avoiding certain tastes. - Standing or posture tapasya: ekasana (standing on one leg), or sitting in challenging postures for discipline. - Bathing and cleansing routines, avoiding comforts, sleeping on bare ground, wearing rough clothing, or enduring heat/cold. - Travel, silence, or limited social contact to reduce sensual or worldly distractions.

• Internal (Antar-tapasya): mental and emotional disciplines

- Right intention and mind control: cultivating forgiveness (kshama), equanimity, and compassion. - Truthfulness (satya) tempered with non-violence: speaking only what is necessary and harmless. - Non-attachment (aparigraha): simplifying possessions, reducing desires, and practicing contentment. - Self-control of senses: restraint of speech, thought, and actions; focusing on spiritual aims. - Study of Jain scriptures, reflection on karma, and meditative practices (samayik) that align the mind with dharma. - Prayer and devotional practices that remind one of the path and cultivate humility.

• Vows and disciplines (Vratas and Anuvrats)

- Vows taken by layJains or ascetics to limit harm and cultivate discipline (e.g., non-violence, truth, non-stealing, celibacy in appropriate contexts, and non-possessiveness). - Anuvrats (small, practical vows) that guide daily conduct and gradually deepen tapasya.

• Desha, Kal, and Bhav-tapasya (contextual discipline)

- Desha (place), Kal (time), Bhav (mental state) based restrictions: practicing austerities appropriate to one’s situation, season, or spiritual goals. - Seasonal or periodic observances like Chaturmas (monsoon-period retreat) for focused spiritual practice.

• Monastic-specific tapasya

- Severe ascetic practices (in Digambar and some Shwetambar contexts): nudity or minimal clothing (Digambar), strict fasting, long fasting periods, and rigorous self-discipline. - For many lay followers, tapasya is milder and adapted to household life, yet still aims at reducing karmic bondage.

Notes on Digambar vs. Shwetambar

• Both traditions agree on the goal of tapasya: purifying the soul and reducing karma.
• The expressions of tapasya differ in emphasis and practice. Digambar monks historically emphasize more austere, sometimes nudity-based ascetic practices, while Shwetambar practices tend to incorporate more cloth and structured vows, with a different interpretation of some austerities. In daily life, both traditions stress self-control, non-violence, truth, and non-attachment, but the specific visible practices may vary by tradition and monastic line.
