While viewing the episodes and getting to behold Shantanu's desire for a Satyavati, and Dhritrashtra and Duryodhan's greed for the throne of Hastinapur, I can't help but ponder over this aspect.
Against the dull backdrop of extreme greed, envy, and deadly conspiracies directed towards attainment of a throne, Devavrat's sacrifice and detachment shines brightly.
Rest of the characters represent the ordinary that gets entrapped in the web of unending desires and unquenchable thirst. Devavrat's metamorphosis into Bhishma is a representation of the extraordinary...an elevation progressing beyond the realms of human limitations.
