Yudhishthira Seeks Expiation – The Ashvamedha Is Proposed
Even after Bhishma's teachings, Yudhishthira continues to feel burdened by the slaughter of Kurukshetra. Kingship has been restored, but his conscience still seeks a way to acknowledge and expiate the violence through which that restoration came.
Vyasa advises him to perform the Ashvamedha, a royal horse sacrifice associated with sovereignty, merit and ritual expiation. The rite requires enormous resources, however, and the war has badly depleted the treasury.
The problem is therefore both spiritual and practical: Yudhishthira wants purification without imposing a new burden on a population already devastated by war.
Vyasa points toward the ancient wealth left by King Marutta, creating a path by which the sacrifice can be funded without extracting the same amount anew from exhausted subjects.
