By Tzvi Freeman
Talk is powerful. Speak bad about someone and you expose all the ugliness in him, in yourself and in whoever happens to be paying attention. Once exposed, the wound begins to fester and all are hurt.
Speak good about the same person, even from afar, and the inner good within him, within you and within all who participate begins to shine.
Likutei Sichot vol. 27, p. 158.
