One who talks sweet does not have an enemy and is blessed with plenty of wealth and good fortune.Lovely Thoughts for Lovely People Just Like You
Speak not harshly to anyone. Those thus addressed will retort. Painful, indeed, is vindictive speech. Blows in exchange may bruise you.
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers
You must speak softly and sweetly and give everyone the respect and attention due to them sincerely. Humility and tolerance must characterise your behaviour as a devotee. When calm descends and the waters are still, the shadow of the Sun within the lake is one full image.
Sathya Sai Baba
Not the fastest horse can catch a word spoken in anger.
One of the greatest victories you can gain over someone is to beat him at politeness.
