She doesn't show any interest in finding out what had happened to Shiva for 24 years, nor does she tell Shiva his wife was not in the house when it was burned down. Shiva seems to be under impression his wife is dead.
Isn't it said that there is no age for learning? Dadi refuses to forget accept - even consider there can be another view other than her own!
Doesn't she know her own son? That he is no frivolous airhead? Why can't she just listen to him for once? She might not agree but so far she has not even bothered to listen!
What is more she constantly tries to turn Rudra against Shiva.
She keeps accusing Shiva of not being a good father to Rudra.
When Shiva says families have rakshaks but rakshaks's don't have families - Dadi mocks& ridicules him - but apart from Rudra, Dadi too has not shown much interest in her family! HER way of doing seva her panth her way is all that seem to matter to her.
Why can't Shiva try to bring water into Saraswati Kund? It is his legacy too, not just Dadi's.
They seem to be making this religion v/s Science argument. Dadi mocks Shiva's education in science (finally this explains the library & all) but she has the narrowest mind ever, so what if it is learned!
More than making Rudra happy it seems to matter to Dadi that she shows to Rudra that she has more concern for him than his father.
Shiva is so focused in his work but Dadi's rant at Saraswati Kund made Shiva forget the machine in the kund!
Nanu's guru said Garuds will be weakened emotionally then they can be defeated - somehow it was assumed to be Maya who will be weakness. What if it is Dadi who is weakness instead? Her rigidity, her refusal to even listen to Shiva, her standing in his way all the time - her trying to turn Rudra against Shiva might be the weakness Garuda's have to overcome.
Maybe Dadi has to see with her own eyes something shocking that will jolt her out of her moral high horse!
