Nirvana Kand (Nirvana Kanda) is a Jain text that describes the places where Jain sages attained Moksha (nirvana). It is traditionally attributed to Acharya Kundakunda, a great Digambara Jain scholar. Most scholars place Kundakunda in the 2nd century CE, so Nirvana Kand would have been composed around that time (roughly 100s CE), though exact dating is not fixed in all traditions. Both Digambara and Śvetāmbara traditions recognize Kundakunda’s authority and discuss his works, including those related to Nirvana Kand, within their own contexts. If you want, I can share the key points it covers (the principal nirvana sites of the Tirthankaras) in simple terms. You can read more about related Jain reflections on this topic here
