Mahatma Vidhura!

Verse 1.15.49 (Srinivas Acharya Prji):

* Vidura, while on pilgrimage, left his body at Prabhasa. Because he was absorbed in thought of Lord Krsna, he was received by the denizens of Pitrloka planet, where he returned to his original post.
* Men are afraid of Yamaraja because it is he only who awards punishment to the miscreants of the material world, but those who are devotees of the Lord have nothing to fear from him. To the devotees he is a cordial friend, but to the non devotees he is fear personified.
* Krishna, wants to see someone who is a pure devotee to do this service and therefore picked up Yamaraja.
* The work of Yamaraja is more intensive cause the number of ppl who are flouting the rules of the Lord is much much more.
* This was so intensive, that Yamaraja wanted to take a break to preach the glories of the Lord. So Krishna sitting in his heart, enacted a pastime where Manduka Muni cursed Yamaraja to be born as a sudra and live in the mortal world for 100 years. And this was Vidhura, thus he got the opportunity to preach the glories of the holy name of the Lord. Because in that life, Lord Krishna gave him so much mercy through His personal association.
* During this time, Aryama (one of the 12 adityas) occupied the position of Yamaraja.
* Vidhura is a mahajan, and expert in neethi-sastra. He always tried to guide Maharaj Dhrtharashtra in the best way possible.
* Being insulted by Duryodhana, he finally leaves Hastinapura for visiting the holy place....
* ...
* Finally, he came to Prabhasa, where being absorbed in the thought of Krishna, Vidhura left his body and went back to his original position of Yamaraja.
* It is more trouble to become envious of the devotees of the Lord, than becoming envious of the Lord Himself.
