In Jain Dharma there is no principle called “Sua” that prescribes not performing puja or not visiting a mandir after the birth of a child. Jainism does not make temple visits or puja compulsory. What matters most is the inner aim: right faith, right knowledge, and right conduct (the three jewels of Jain path) and living a life of non-violence, truth, and self-restraint.

Key points to understand:

• Temple visits and puja are common expressions of devotion, but they are not obligatory in Jainism. Families may choose to perform rites at home or in a temple, depending on local tradition and personal comfort.
• For a newborn, Jain traditions do include auspicious rites and rituals centered on the child’s well-being and the family’s spiritual aspirations. These rituals vary by community and lineage (Digambar vs. Shwetambar), but they do not teach that one must completely avoid temples or puja.
• The emphasis is on cultivating right conduct from infancy—kindness, mindfulness, and respect for all living beings—rather than on a specific rule about mandir attendance.

Regarding Digambar and Shwetambar differences:

• There are variations in ritual practice and emphasis between these two traditions, especially in certain rite formulations and sequences. The core Jain aim—ahimsa, anekantavada (many-sided truth), and self-purification—remains the same.

If you’re looking for exact scriptural references or a precise description of newborn-related rites in a particular tradition, I can provide that, focusing strictly on authentic Jain sources.
