SB 10.10.41
sadhunam sama-cittanam
sutaram mat-krtatmanam
darsanan no bhaved bandhah
pumso ’ksnoh savitur yatha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated by Caitanya Mahaprabhu (Cc. Madhya 22.54):
‘sadhu-sanga,’ ‘sadhu-sanga’ sarva-sastre kaya
lava-matra sadhu-sange sarva-siddhi haya
If by chance one meets a sadhu, a devotee, one’s life is immediately successful, and one is freed from material bondage. It may be argued that whereas someone may receive a sadhu with great respect, someone else may not receive a sadhu with such respect. A sadhu, however, is always equipoised toward everyone. Because of being a pure devotee, a sadhu is always ready to deliver Krsna consciousness without discrimination. As soon as one sees a sadhu, one naturally becomes free. Nonetheless, persons who are too much offensive, who commit vaisnava-aparadhas, or offenses to a sadhu, will have to take some time before being rectified. This is also indicated herein.
