SB 3.10.2
ye ca me bhagavan prstas
tvayy artha bahuvittama
tan vadasvanupurvyena
chindhi nah sarva-samsayan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O greatly learned one, kindly eradicate all my doubts, and let me know of all that I have inquired from you from the beginning to the end.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vidura asked all relevant questions of Maitreya because he knew well that Maitreya was the right person to reply to all the points of his inquiries. One must be confident about the qualifications of his teacher; one should not approach a layman for replies to specific spiritual inquiries. Such inquiries, when replied to with imaginative answers by the teacher, are a program for wasting time.
