sadhunam sama-cittanam
sutaram mat-krtatmanam
darsanan no bhaved bandhah
pumso 'ksnoh savitur yatha

When one is face to face with the sun, there is no longer darkness for one's eyes. Similarly, when one is face to face with a sadhu, a devotee, who is fully determined and surrendered to the Supreme Personality of Godhead, one will no longer be subject to material bondage.

(Srila Prabhupada's rendering of SB 10.10.41)
