In the Sabha Parva of the Mahabharata, Draupadi asks the assembly whether Yudhishthira could stake her after he had already lost himself. Bhishma replies. “O blessed one, morality is subtle,” he says, in the Ganguli translation. “I therefore am unable to duly decide this point that thou hast put.”
He sets out the arguments on each side. Then he says it again: “Therefore, I can not decide this point.”
