Nithya Karma’s in Ramayana
Though Shri Mahavishu took 6 avatars before Rama Avatar, only in this he born and lived as other humans. All other avatars were need of that moment only.
Though all the Puranas Sasthras and other books Describing the Karmas which we need to do in days to days life, we have a doubt whether we can do that or not?
If we think that those karmas are only for the purpose of Upanyasa , it will be a great dishonour to the Rishis who gave them to us. All the Karmas given by them can be done even today. They have given only the Karmas which we can follow now. If we say we cant do that today , then its our weakness only. Since you are not following a particular Karma or Dharma , you cant say that Dharma or Karma is Entirely Wrong.
Rama Avataras main aim to show that world , every one should and can follow the Nithyakarma without Fail.
You may say that i don’t have time . My Day is full of work in office and in home. Yes its true. Similarly in Rama’s life also, he face enormous problem. He did not spend his life in palace alone. He went to Aranyas, Sea and faced lot of problems and difficulties. But there was not even a single day in his life, in which he did not follow the Nithyakarmanusta.
