While performing pooja which gotra should told by saitwal jain

While doing pooja, a Saitwal Jain should usually mention their own family gotra / kul-gotra as traditionally known in the family.

If your family has a specific gotra, say that one. If no fixed gotra is used in the family, many people simply say their own name and family identification in a respectful way.

In Jain pooja, the main thing is bhav, shuddhi, and devotion; gotra is secondary to sincere worship.
