Yes. In Jain practice, it is common to perform a simple home puja (pūjā) and to offer ritual items like water or arghya as part of domestic worship. Whether arghya is included and how it’s done can vary by family and by tradition (Śvetāmbara vs. Digambar), but it is not forbidden.

On Mahavir Nirvana Day (Nirvana day), many Jains observe in the evening with prayerful activities such as:

• Pratikraman (confession and repentance)
• Samayik (meditation and equanimity)
• Reading or listening to accounts of Mahavira’s life
• Fasting or reduced meals as a personal vow (optional)

Key point: the exact rites and emphasis can differ between Digambara and Śvetāmbara communities and between families. If you have a specific tradition in your locality, it’s best to follow the guidance of your local Jain guru or family elders.

If you’d like, I can point you to a Jain Knowledge page that discusses home puja and Nirvana Day practices in more detail.
