In plain words
Dharmaja folded his hands: ‘O Indra! Neither my wedded wife nor my brothers could follow me. But this dog has followed me all along. Seat first in it the dog that followed me, and afterwards I will sit,’ he said. As these words full of sacrifice came from Dharmaja's mouth, the dog took on the form of Dharma. He was Yama Dharmarāja himself. That Yama Dharmarāja: “Dharmaja! I came along with you to test how your Dharma would hold to the very end. What is my work? ‘Dharmayeva hatohanti’: to slay whoever violates Dharma. ‘Dharmo rakṣati rakṣitaḥ’: to protect those who have protected Dharma. Because you have followed me all along, I am your servant,” he said. Then: ‘I followed you in order to make your Dharma known through the world. At long last it has become known to the world that you are of so pure a heart. So now I take my leave,’ and with that Yama Dharmarāja vanished.
Prāṇa, apāna, vyāna, udāna and samāna are the five vital breaths in the human body
If we go a little deeper into this story and inquire: who could not follow Dharma? Who could not enter heaven? The one with a sense of difference, the one full of self-assurance, the one proud of his looks, the one who breaks his word, the one who lives for food: these five cannot follow Dharma and cannot reach heaven. Teaching this Satya, Dharmaja entered heaven. These five are prāṇa, apāna, vyāna, udāna and samāna. When it is told as no more than Dharmaja, Draupadī, this one and that, you all take it for stories. No, no: this is our true history! Prāṇa, apāna, vyāna, udāna and samāna: these five are in the human body as the five vital breaths. We must give each thing its fitting value. But we are not giving it. We founded this Institution with this very aim: that when you set your whole lives on this sacred path, you would take shape as students who are an ideal to the world and to society.
