Shatrunjay Tap means a vow of penance and devotion performed in honor of Shatrunjay Giriraj (Palitana), the supreme tirth of Bhagwan Adinath. Its core aim is “inner victory” over anger, pride, deceit, and greed through bhakti, self‑restraint, and yatra of Giriraj.

What it usually includes (Details can vary by sangh and guru‑parampara; take pachakhan from your guru or sanghpati.)

• Sankalp and pachakhan: Taking a clear vow (niyam) for the duration and form of the tap.
• Ahar tap:

- Upvaas (full fast), Ekasana (one meal), or Ayambil (plain one‑time meal) as per capacity. - Chauvihar or Tivihar, and boiled water discipline during daylight. - Optional tyag like avoiding root/green items, sweets, or taste‑enhancers.

• Shatrunjay yatra (tirth‑bhav with discipline):

- Climb from Taleti with shraddha and ahimsa‑maryada. - Maintain shauch, modest speech or maun, and do darshan of Adinath Bhagwan and other temples as per your niyam. - Complete return the same day; keep the hill’s maryada (no casual eating/loitering).

• Daily sadhana:

- Navkar‑jap, Samayik/Pratikraman, Chaitya‑Vandan, stavan, swadhyaya. - Bhav‑puja of Tirthankar and cultivation of kshama, vinay, and aparigraha.

• Daan and seva:

- Ann‑daan, tirth‑seva, and respect to sadhus‑sadhvis and shravak‑shravikas.

• Utsarg/parna:

- Conclude with proper parna as per pachakhan, with gratitude and kshamapana.

Common ways people observe it

• One‑day Shatrunjay Tap: Upvaas/Ayambil with Giriraj yatra and bhakti that day.
• Short series: A set number of Ayambils/Ekasanas combined with one or more yatras.
• Long anushthan: Multiple yatras (e.g., vowed counts) over time with niyams on food, speech, and seva.

Traditions

• Shwetambar (especially Murtipujak) households commonly use the term “Shatrunjay Tap” for such combined yatra‑plus‑niyam observances centered on Adinath Bhagwan at Shatrunjay.
• Digambar devotees also revere Shatrunjay and observe yatra, fasts, and bhakti; liturgical details and terminology may differ. In all traditions, maryada of the tirth and same‑day descent are respected.
• Always follow the maryada of your local sangh and the guidance of your guru for the exact niyams and permitted practices.
