sri-suka uvaca
ity anamya tam amantrya
viduro gajasahvayam
svanam didrksuh prayayau
jñatinam nirvrtasayah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: Vidura thus offered obeisances unto the great sage Maitreya and, taking his permission, started for the city of Hastinapura to see his own kinsmen, although he had no material desires.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When a saintly person wants to see his kinsmen, he has no material desire to see them. He simply wants to give them some instructions so that they can benefit. Vidura belonged to the royal family of the Kauravas, and although he knew that all the family members were destroyed at the Battle of Kuruksetra, he nonetheless wanted to see his elder brother, Dhrtarastra, to see if he could deliver Dhrtarastra from the clutches of maya. When a great saintly person like Vidura sees his relatives, he desires only to deliver them from the clutches of maya. Vidura thus offered his respectful obeisances to his spiritual master and departed for the city of Hastinapura, the kingdom of the Kauravas.
