Probably, most of us say things in private we wouldn't dare utter in public. But, is that acceptable or morally healthy? Hindu texts indicate that all speech reveals who we are. The Upanishads say our actual character is made up of our deepest desires; those desires manifest as our words and actions, which, in turn, create our destiny.
The human heart is very sensitive to words. Few things can dishearten an inspired heart as much as callous or critical words. And conversely, few things can enliven a depressed heart as much as comforting or compassionate words.
