Lagta hai aapka vaakya adhoora रह गया. Sandesh ka saar yeh ho sakta hai:

Purv‑kal mein sandhyā samay gharo mein ghanti bajti thi. Iska uddeshya tha sabko dhārmik kriyāon ke liye bulāna—jaise Devāsī Pratikraman, Samayik, aur Aarti/Mangal Divo.

• Jain paramparā mein sandhyā ke samay Devāsī Pratikraman ki pratha hai; yeh din bhar ke aparādhoṅ ka ālocan‑pratikraman hai. Śvetāmbara aur Digambara donoṅ mein iska mūl bhāv ek hi hai, yadyapi vidhi aur samay meṁ kuch chhote antar ho sakte hain.
• Kai gharon aur derāseroṅ meṁ is samay Aarti aur “Mangal Divo” bhi hotā hai, jiske daurān ghanti bajākar shubh sankalp kiyā jātā hai.
• Is paramparā ka mūl tatparya: ahinsā, samata (equanimity), kṣamā‑yāchanā aur apraadhon se virati ka sankalp.

Adhik padhne ke liye:

• Pratikraman ka mahatva aur samay:
• Sandhyā (Devāsī) Pratikraman ke samay ka sūtra‑svarūp margdarshan:
• Samayik/Pratikraman ki saral vidhi:
• Mangal Divo (sandhyā aarti ke daurān gāyā jātā stavan):

Yahi Jain paramparā ka sādhāraṇ roop hai: sandhyā meṁ ghanti bajti thi/bajti hai, sabhi sādhanā ke liye smaraṇ aur āhvān ke rūp meṁ.
