In English, "punya tatva" means "the principle of merit" or "the substance of virtue."

In Jainism, "punya" refers to meritorious karma or the positive spiritual energy that results from good deeds, right conduct, charity, non-violence, and other virtuous actions. "Tatva" means principle or fundamental reality. So, "punya tatva" is one of the fundamental tattvas (principles) in Jain philosophy, representing the accumulation of good karma which leads to happiness and favorable circumstances in future births.
