kaya vrttya vartitam vas
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While traveling on the surface of the earth, how did you maintain your livelihood? At which holy places and pilgrimage sites did you render service?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vidura went out from the palace to detach himself from household affairs, especially political intrigues. As referred to hereinbefore, he was practically insulted by Duryodhana’s calling him a son of a sudrani, although it was not out of place to talk loosely in the case of one’s grandmother. Vidura’s mother, although a sudrani, was the grandmother of Duryodhana, and funny talks are sometimes allowed between grandmother and grandchildren. But because the remark was an actual fact, it was unpalatable talk to Vidura, and it was accepted as a direct insult. He therefore decided to quit his paternal house and prepare for the renounced order of life. This preparatory stage is called vanaprastha-asrama, or retired life for traveling and visiting the holy places on the surface of the earth. In the holy places of India, like Vrndavana, Hardwar, Jagannatha Puri, and Prayaga, there are many great devotees, and there are still free kitchen houses for persons who desire to advance spiritually. Maharaja Yudhisthira was inquisitive to learn whether Vidura maintained himself by the mercy of the free kitchen houses (chatras).
