Can you clarify what you mean by “navkarsi”? In Jainism, the closest terms are Navkar Mantra (Namo Arihantanam, etc.) and various recitations or rituals like samayik. If you’re asking about a specific practice that happens at 3 PM, please share a bit more detail (e.g., is it a particular stotra, a jain temple routine, or a layperson’s daily practice). I’ll explain exactly what it is and its correct meaning.
