I have been reading "The Difficulty Of Being Good" by Gurcharan Das. He brings out episodes from the epic, highlighting the question(s) of Dharma.
Dharma is subtle.
The question of Dharma is raised repeatedly ; by Draupadi, by Arjun, by Yudhisthir, by Bhishma, by Karna. It is never clearly answered.
It is for each of us to understand our Dharma, our duties, our responsibilities.
