Gautama Buddha – The dreadful habit of doubt Share this quote: There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills. – Gautama Buddha (563 BC-483 BC) Is this quotation insightful, though-provoking, useful? Click on a star to rate it!
