Here is a very simple / small Chaityavandan vidhi (Śvetāmbara Mūrtipūjak style), which you can do at home or in derāsar if you don’t know full sutras yet.

---

1. Preparation

• Take bath (or at least wash hands, feet, mouth).
• Wear clean, simple (preferably white) clothes.
• Sit on a clean āsan, facing Jina idol / photo or direction of derāsar.
• Keep mind calm: “Ab main thodī der ke liye sirf Jinendra bhakti karūṅgā/karūṅgī.”

2. Small Chaityavandan (Laghu Vidhi)

(1) Nissihi & Small Pachchakkhān (mentally)

• Think: “Ab jitnī der Chaityavandan karūṅgā/karūṅgī, main sabhī viṣay-vikār se alag rahūṅgā/rahūṅgī.”

(2) Navkār Mantra

• Sit straight, fold hands.
• Navkār Mantra 3, 9, or 27 times with full dhyān on Panch Parmeshthi.

(3) Kayotsarg + Logassa (if you know it)

• Stand in Kayotsarg (seedhe khade, hile nahiṅ, āṅkh halkī band ya nīche).
• If you know: Logassa sutra once, slowly.
• If you don’t know Logassa: just stand silently for 1–2 minutes, remembering 24 Tirthankar Bhagwān.

(4) Khamāsamano (if known)

• Sit again.
• Recite Khamāsamano sutra (asking for forgiveness from all sadhus/sādhvīs).
• If you don’t know the sutra, simply pray:

- “Jo galti kisi bhi jīv ke prati hui ho, kṛpā karke mujhe kṣamā kareṅ, main bhavishy meṅ sudharne kā saṅkalp kartā/kartī hūṅ.”

(5) Chattāri Maṅgalam / Maṅgal Pāṭh

• Say (if you know):

- Chattāri Maṅgalam - Pañchindiya (optional, if known)

Or in very simple Hindi:

• “Arihant, Siddh, Āchārya, Upādhyāy, aur sabhī sādhus–sādhvīoṅ ko main vandan kartā/kartī hūṅ. Mujhe bhī unke jaise shuddh guṇ milne kā bal mile.”

(6) Prārthanā & Maitrī Bhāvanā

• Do a short prayer:

- “Hey Jinendra Bhagwān, mujhe ahimsā, satya, aparigraha aur samyak dṛṣṭi–chāritr kā bal dijiye. Main sab jīvoṅ se maitri rakhūṅ, kisi se dvesh na karūṅ.”

• End with:

- “Micchāmi Dukkaḍaṁ” – “Jo bhī galti soch, vachan, kāyā se hui ho, uske liye main kṣamā māngtā/māngtī hūṅ.”

3. For Very Short Time (Ultra-Small Vidhi)

If you have very little time, you can do this minimum:

1. Navkār Mantra (9 times)
2. 1–2 minutes Kayotsarg (standing still, remembering Tirthankars)
3. “Micchāmi Dukkaḍaṁ” with true repentance

This is not a full Chaityavandan, but a short bhāv-pūrvak version for busy days.
