Lagta hai aap “Surya‑uday (Suryoday) ka pachkan” pooch rahe hain. Jain paramparā meṅ isse aam taur par “Navkārsī nu Pachkhan” (Navkarsi) ke roop meṅ liyā jātā hai. Niche seedhi bhāṣā meṅ sankshipt roop diye gaye hain. (Yadi aapka arth Surya‑ast ke baad ke niyam haiṅ, to vah “Tivihār/Chovihār” ka pachkan hotā hai—unke roop bhi niche haiṅ.)

2) Surya‑ast ke baad ke niyam a) Tivihār (Trivihār) ka pachkan

Paramparā‑sangat baateṅ

• Shvetāmbara aur Digambara donoṅ meṅ shabd‑rūp/alpa vākya‑bhed ho sakte hain, par āśaya ek hī hai: saiyam, ahimsā aur savadhān bhog.
• Pachkan sadaiv shraddhā se, subah/pratikraman ke samay ya Guru/pratimā/sāstr ke sāmne liya jātā hai.
