In plain words
They are set on tormenting the Pāṇḍavas, who are Dharma embodied. Through infatuation with your sons, through pride, through your attachment to them, you are going astray. One who drinks poison dies alone. But when, in the rule of a kingdom, the mind takes a crooked path, the whole kingdom wastes away. All the people perish. The king, too, is destroyed. Why do you, with your own hands, bring your kingdom to dust through this evil counsel and this evil nature? You are destroying your whole line. This is not right. Recognise the truth,” he warned. Unable to bear his grief, he went on in his agitation to say more. “It was because you were the eldest son, and because he had no wish for the kingdom himself, that King Pāṇḍu crowned you. One born blind, one born deaf, one who is mad, one who is unsteady: none of these has the right to rule. Whenever such kings rule, they destroy everything. It is because the kingdom was given to one like you that you are destroying yourself with your own hands. Dharmaja has the quality of kṣamā in full measure. Seeing that kṣamā in him, you think Dharmaja a coward. But kṣamā is not something that shows on the surface. It is the sword of peace. It is the crown on Dharmaja’s head. No one can say at what moment this kṣamā will strike you down, and yet, taking it for cowardice, you set about tormenting them. Very soon the kṣamā of the Pāṇḍavas will bring you to utter ruin,” Vidura warned Dhṛtarāṣṭra. Just as he said, it was the kṣamā of the Pāṇḍavas that won them victory. From then on the sacred strength and power of the Pāṇḍavas spread through the world. These four kinds of purity are the very ground of kṣamā.
Good conduct, right living: that is Dharma
The chief ground of these purities is Dharma. And it is from this Dharma that Satya begins. From Satya, in turn, Dharma begins. The tree from the seed, the seed from the tree.
