Short and clear reply:

1. General rule in practice (especially in Śvetāmbara mūrtipūjak tradition)

- First in the morning: snātra/abhishek + dravya-pūjā are done on the main Pratimā. - After Aangi (āṅgī) is applied (decoration with candan / āstagandha etc.), that same Pratimā is not used again for jal‑abhishek or full dravya‑pūjā for the rest of that period/day. - Only aarti, maṅgal divo, stavan, pradakṣiṇā, namaskār, mental bhakti are done in front of that Pratimā.

So: - No, full dravya-pūjā (with jal, candan, etc. touching the idol) is not normally done on the same Parmātmā after Aangi. - Yes, bhāv‑pūjā (mental worship, stavan, aarti, etc.) is absolutely allowed and encouraged.

1. Is there direct “āgamic” (canonical) śāstra that says this?

- The early Jain Āgams and basic Digambar śāstras describe Jina‑pūjā, snātra‑pūjā, aṣṭaprakārī‑pūjā etc., but they do not mention the modern decorative Aangi in detail. - So there is no direct canonical line like: “After Aangi you must not do pūjā.” - This niyam is based on: - Maryādā (traditional temple discipline) fixed by Āchāryas and sangh. - General śāstric principles: - Jinendra pratima is for śānta, śuddha darśan, not for unnecessary repeated handling. - Once śṛṅgār (divine adornment) is done, repeatedly washing or smearing over it is considered asammāna (disrespect) to that bhakti‑upchār.

So the “proof” is indirect: - Śāstra gives principles of maryādā, śauca (cleanliness), and pratima‑samman. - Āchārya‑nirdhārit paddhatis and derāsar‑maryādā apply these principles and say: - “Aangi ke bād is pratima par punah dravya‑pūjā na karein; keval darśan, aarti, stavan karein.”

1. Difference of traditions (Digambar / Śvetāmbara)

- Śvetāmbara mūrtipūjak: - Elaborate Aangi is done, especially in Paryushan, etc. - After Aangi: no new snātra / abhishek / aṣṭaprakārī‑pūjā on that same idol till Aangi is respectfully removed. - If snātra is to be done again, it is usually on a separate snātra‑murti without Aangi. - Digambar: - Generally very simple candan / tilak instead of elaborate colour Aangi. - Multiple abhishek may be done according to local maryādā, but still with respect to shṛṅgār and pratima‑samman.

1. Practical takeaway for you

- If the main murti has Aangi, you should: - Not do jal‑abhishek / full dravya‑pūjā on that murti. - You can and should do: - Namaskār, Navkār mantra, stavans. - Aarti, maṅgal divo (as per local rule). - Dhyan and mental pūjā. - For dravya‑pūjā, use: - A separate snātra‑pratimā, or - A yantra / patta if that is the maryādā of your derāsar.
