In Jain Dharma, there is no Shraddh like in Hindu tradition, but there are very meaningful Jain ways to remember your father and create punya in his memory.

1. Understand Jain view first

• The soul (aatma) of your father has already taken a new birth according to its own karma at the very moment of death.
• No later ritual can change his next birth or directly give him moksh. ( jainknowledge.com)
• Whatever you do now mainly purifies your karma and is done with respectful remembrance of him.

2. Daily simple prayer you can do

You can do this every day, at home or in temple:

1. Sit quietly, join hands, and recite:

- Navkar Mantra (Namokar Mantra) a few times. - If you know, you may also recite small Jain sutras or stavans your father liked.

1. After that, close your eyes and with folded hands think:

- “If I ever hurt my father by mind, speech or body, I ask forgiveness from his soul.” - “From my side I forgive him for any hurt. May his soul move ahead on the path of liberation.”

1. End with “Michchhami Dukkadam” from your heart.

This is a very pure Jain “prayer” for a departed parent.

3. Punya-karmas in his memory (best “Shraddh” in Jain way)

Instead of Shraddh rituals with food for “pitru”, Jain Dharma emphasizes:

1. Daan (charity) with ahimsa-bhav

- Help the poor, support animal welfare, donate to Jain pathshala, upashray, gaushala, or for scriptures in his memory. ( jainknowledge.com) - Before giving, recite Navkar and mentally say: “Whatever small punya comes from this, may it become a cause for my own right faith and for the uplift of all souls.”

1. Jiv-daya (compassion to living beings)

- Avoid parties, meat, alcohol, and himsa in his remembrance. - Free birds/animals from slaughter where possible, sponsor medicines, etc.

1. Swadhyay, Samayik, Pratikraman

- Fix one day (e.g., tithi of his death or his birthday) for extra samayik or pratikraman dedicated to inner purity. ( jainknowledge.com)

1. Keep his good gun (virtues) alive

- If he had special good qualities (satya, ahimsa, daya, simplicity), consciously practice those. - Teaching children/grandchildren to follow Dharma is one of the highest tributes.

4. About Shraddh / Pitru Paksha specifically

• Shraddh, Pitru Paksha, and formal ancestor-worship rituals are not part of Jain Dharma. ( jainknowledge.com)
• Both Digambar and Shwetambar traditions agree: such Shraddh rites are not prescribed in Jain scriptures.
• Some families may still keep a cultural habit, but it is not a Jain religious requirement.

If you wish to stay close to “shuddh Jain dharm”, you can:

• Avoid Shraddh-type rituals meant to “feed” or “satisfy” ancestors.
• Focus on Navkar Mantra, forgiveness, charity, jiv-daya, swadhyay, and simple remembrance with vairagya.

5. Simple example you can follow on his barsi / special day

On his death anniversary or birthday:

1. Take Jain-style vow for the day:

- No unnecessary himsa, no anger if possible, simple food, avoid show.

1. Morning:

- Snan, clean clothes, light diya (without himsa as far as possible), recite Navkar Mantra 9–27 times. - Do a short samayik (10–48 minutes) if you can.

1. Daytime:

- Do daan (money, medicines, grain for animals, etc.) in his memory.

1. Evening:

- Do Pratikraman (if you know it) or at least sit quietly and do: - Navkar Mantra - Heartfelt kshama-yachna (asking/ giving forgiveness) towards him.

This is a very good, fully Jain way of “prayer / shraddh” for your deceased father.

If you tell me your tradition (Digambar / Shwetambar / Sthanakvasi), I can suggest an even more specific set of sutras or practices commonly used in that sangh, but even without that, the above is fully acceptable in all Jain traditions.
