Though you speak unkind words
on the face of of a man but never
speak behind one's back. Though every
word is full of kindly virtue but it is
treated as back-biting may betray
his heart.

Thrrukural 19.184-186


Word have power both to destroy
and heal. When words are both true
and kind, they can change our world.

Gautam Budhha.


Words are the most powerful drug used by mankind.
