During the little time available, if you don't think of some good subject, but merely recollect the ignorant prattle of others, it is as if you too joined in the blame game. This is harmful to a devotee. One word following another produces anger and pain. The path of devotion is designed for suppressing, not developing these qualities. The talk of the fault finders is like the sound of bronze. Cheap metals make more sound. Gold which does not make sound is very valuable. So too, true devotees will remain mute, following the path of silence. Their tongue will be fully engaged in the repetition of the essential greatness of the Lord's Name. It is best that they have no respite for any other word.  So do not permit the words of the bronze-voiced persons to enter your ears, instead fill them with the Name of the Lord. 

-Divine Discourse,  Sandeha Nivarini.

A pure heart is the best mirror for the reflection of truth. - Baba
