It's always what's inside us is reflected in our environment... We think or see what we want to see... it's our choice to see stuffs positively or see the negativity in the events.. And this the rule of environment or Prakriti...
but the rules of society, made by human beings may twist the rules of Prakriti, for good or for bad ...
Sita's knowledge is limited to Prakriti.How much she trusts the praja. She knows if she wants to see positivity she needs to be positive from within , but she forgets that whole world is not positive from within, whole world is not "Ram"
And dats what happens, they fail her, they fail their queen by questioning her purity. Thus the concept of inner happiness manifesting as outer happiness, the rule of Prakriti is twisted by the rigidity of society... infact it's manifested in a opposite way, the negativity inside them shows up..
That's where Ram, who understands both Prakriti nd Sanskriti need to take charge in a way that both are not hurt.
And how he does that, we all know..
Another thing which struck me was the coexistence of Prakriti nd Sanskriti. No one is superior both r equal. Even Prakriti(Sita) protects Sanskriti(Ram) like in S Ravan case nd even Sanskriti protects Prakriti like in Ravan case, the real Ravan nd the Ravan in the minds of Ayodhya vasis.
Coming to moon. I am borrowing Charvi's theory here... Dhobi said the full moon's blemishes can be seen better. The same moon which is cherished by many lovers as sign of love (purest feeling) is called blemished by others.. As we see , what we choose to see.
So it's the sun who protects moon from the evil eyes, those who can't see her purity. It hides it under its protective rays and finally when those evil eyes sleep, in the night, the moon is set free. And only those who can admire it's real beauty can see it. That's how Ram(sun) hides Sita(moon) from the evil eyes and sets her free for those who can see her real beauty. They r not seen together physically but still are together...
