Jain dharm ke anusar 14 Purva bahut prachin granth the, jo aaj humare paas nahi bane. Inka “punaravartan” ya punarjagran ki koi nishchit tithi ya samay-sima dharmik shastraon me likhi nahi hai. Ajsak ke Digambar aur Shwetambar dvaaron me is vishay par vishesh roop se alag-alag vyakhya hoti hai, par aam taur par yeh maana jaata hai ki Purva ka vikas aur unka samay-samay par punarjagran ki ek spasht ghatna ki tareekh nirdharit nahi ki gayi hai.

Yadi aap Digambar ya Shwetambar ki vishesh dharmik vyakhya chahte hain, to bataye main us hisaab se spasht kar dunga.
