In Vedanta philosophy, the different schools of thought like Vishishta-Advatia, Advaita, Dwaita etc. agree upon the following facts:
1. There are constant numbers of jeevatman in the universe/Samsara (consisting of all 14 Lokas)
2. After Moksha, a jeevatman cannot return to any other state (but individual can roam around if he wants to).
So looking for the future with these constraints, a time will come when all jeevatmans present in the whole creation would get moksha. What would happen when such a saturation condition occurs?
The only solution I see is to again create more jeevatmans (since bramhan is all powerful and all pervading). Bramhan can pull this off, but why is he not allowed to create more of jeevatmans?
