I’m sorry for your loss. Here is a simple, tradition‑faithful Jain way to proceed after a parent’s death.

Core understanding

• The soul (jīva) is eternal. Death is only a change of body according to one’s own karma. The most helpful thing you can do is keep equanimity (sāmāyik bhāva) and create pure merit (puṇya) through right conduct.

Immediately

• Maintain calm and recite the Navkār Mantra softly. Avoid loud lamentation; it disturbs passions (kaṣāyas).
• Offer forgiveness from the heart: “Michchhāmi Dukkaḍaṁ.” Let go of every grievance.
• Keep the environment simple and pure: light, clean cloth, no ostentation.

Funeral (Antyeṣṭi)

• Perform a simple, non‑violent cremation as early as practical.
• Avoid non‑Jain rites (e.g., rituals claiming to change the departed soul’s destiny). Use the occasion for restraint, prayer, and compassion.
• If possible, direct expenses from showy ceremonies to jīvadayā (saving living beings), panjarāpol, education, or health aid.

Daily practices in the days after

• Navkār Mantra jāp (as per capacity, e.g., 108 times), sāmāyik, pratikramaṇ, svādhyāy, and chaityavandan.
• Do śānti‑pāṭha/vidhān and offer dān with pure intent. The benefit purifies the doer; it does not alter the departed one’s karma.
• Live simply: avoid celebration, entertainment, and unnecessary new purchases for some time; focus on study and virtue.

Tradition notes

• Śvetāmbara: Many families do Snātra Pūjā, Śānti‑kalash, or Siddhachakra Pūjā and a simple prabhāvanā. Community customs like a “tēravi” meal exist, but scripture emphasizes simplicity and spiritual focus.
• Digambara: Emphasis on sāmāyik, svādhyāy, śānti‑pāṭha, and dān. Some communities ask the closest mourner to refrain from image‑worship for a few days; this is a community custom, not a core scriptural rule.
• “No green” (avoiding leafy vegetables) on the death tithi or for a few days is a community practice to reduce hiṁsā; it is optional.

Annual remembrance (tithi)

• On the parent’s death tithi each year: observe a fast or eat very simple sāttvik food, do pratikramaṇ, Navkār jāp, svādhyāy, and jīvadayā. Dedicate the puṇya with a quiet śānti‑pāṭha.

What to avoid

• Costly show, superstition, and any rite claiming to “transfer” karma.
• Harmful offerings (flowers wasted in bulk, leather, silk, etc.). Prefer cleanliness, restraint, and compassion.

Helpful verses to recite

• Navkār Mantra:

“ṇamō arihantāṇaṁ, ṇamō siddhāṇaṁ, ṇamō āyariyāṇaṁ, ṇamō uvajjhāyāṇaṁ, ṇamō lōē savva‑sāhūṇaṁ.” Meaning: Bowing to Arihants, Siddhas, Āchāryas, Upādhyāyas, and all Sādhus destroys sins and leads toward liberation.
