If you meant observing the tenth day (Dashami) of a Jain festival at home, a clear Jain approach is to align with the tradition around Samvatsari, the forgiving day at the end of Paryushan/Das Lakshana. Here is a simple, home-friendly guide in line with Jain practice:

What to do at home

• Prepare a clean, quiet space for prayer or samayika. Light a small lamp and keep a clean cloth and a small image or symbol of a Tirthankara if you have one.
• Pratikraman (confession and repentance)

- Recite a short, sincere Pratikraman focusing on forgiveness for any harm done to living beings, directly or indirectly, during the day. - If you have a regular Pratikraman chant, recite it. If not, a simple reflection on non-violence, truth, purity, and respect for all beings is good.

• Namokar Mantra

- Begin with the Navkar Mantra (Salutations to the Pancha-Parameshthi) and reflect on its meaning: honoring the Arihantas, Siddhas, and all beings.

• Forgiveness prayers (Kshamavani)

- On Samvatsari or Dashami, say “Kshamavani” (forgiveness) to family members and others you may have harmed knowingly or unknowingly. If possible, say it aloud and with a calm heart.

• Austerities at home (optional but meaningful)

- Observe a light fasting or a simple, limited meal if you normally fast on such days. - Eat with non-violence in mind—vegetarian, mindful of not wasting food.

• Puja and offerings

- Offer water to a plant or a small symbol of life nearby; keep the focus on non-violence, self-purification, and gratitude.

• Reflection on non-violence and ahimsa

- Spend a few minutes contemplating ways to harm none today, in speech, thought, and action, and resolve to practice more compassion.

Simple Samayik (optional)

• If you have a booked samayik session, set a small, quiet period (stillness, reading or listening to a short Jain dharma discourse) for the duration you’re comfortable with.
• Conclude with a short dedication to living beings’ welfare and your intention to reduce harm.

Notes

• Dashami can refer to the tenth day in many observances; in Jain practice, the meaningful spiritual focus around the end of Paryushan is Samvatsari, a day for forgiveness and purification. If your question is about a specific local or family custom labeled “Dhoo Dashmi,” you may be following a regional practice; in that case, I can help you align it with core Jain values of ahimsa, truth, and purification.

If you want, tell me which exact day or festival you’re referring to (the dates, or the temple/region you follow), and I’ll tailor the guidance precisely in line with Jain dharma.
