The Mahabharata is an Indo-Aryan epic about the dynastic struggle by Pandavas & the Kauravas for the throne of the Kingdom of the Kuru, held by Dhtrarastra, the blind king of the Kauravas.
In it Dhtrarastra, the blind King of Kauravas asks for a report from Sanjaya his chief minister who has the gift of seeing at a distance:
The first couplet of the first chapter of the Bhagavad Gita is:
In the Kingdom of the Kurus, the land of Dharma War-like stand
My men and the Sons of Pandu; what did they do next, O Sanjaya?
What does Dharma stand for in the context of the Gita? I can discern three major concerns:
Arjuna questioning the consequences of the impending war in the first chapter - The Grief of Arjuna
Krishna counselling Arjuna on his duty as a warrior, and
and on moksha (religion).
The ethical dilemma in the Gita relates to the first two. Thus Dharma as what is right, righteousness; and Dharmas as duty, here as war; thus right vs might and Dharma encapsulates both senses.
At least as I understand it.
Aesthetically, this combination of meanings reminds me of the Sublime which combines the Beautiful/Good with the Terrible/Majesty.
Is this the best way to understand Dharma in this first couplet in the context of the Gita as a whole?
