I must admit, I was confused watching the episode. In the idea to prove the samsarik aspect of Shiva, parvathi is now crossing the limits of the dharma dictated. Wife should never ever tell her maternal folks about her living conditions. They may derive their own opinion. How can an embodiment of dharma would refuse gifts from her mother because there is no place to put them. I guess life did take a full circle. The mother became the daughter and the daughter became the mother :)
On the other hand loved the message Shiva gave to his kids. Happiness comes from with in. See the most wonderful things in the simplest of things. Happiness and sadness are don't derive from material things rather they are state of mind.
Raavana, confused me as well. He made me wonder, I guess I need to wait and see where this is going. For Raavan, Shiva is his father , his guru, his everything. He really mortalizes Shiva. Hence, he was thinking of giving him every worldly delight as possible. Or at least that is how I perceived. I did see Rishi Markandeya's POV as well. This is why I like this show. Challenges one who is committed a single train of thought.
