Duryodhana’s retreat to the lake seems unusually introspective of him, given how vocal he was previously about charging into battle, even when it wasn’t wise. This passage shows how grief and loss can affect even the most stubborn people, including Duryodhana. Water has many spiritual connections in the poem, usually to purification and new life, and Duryodhana’s trip to the lake seems to be a much-too-late attempt for him to reflect on his actions and perhaps even atone for them.
