Our mind is a devil which is in constant interaction with all surroundings. We literally have thousands of thoughts filling up our mind with some useful thoughts but most of it with garbage. What to keep and what to keep out is a constant exercise we undertake everyday. When we are dealing with people , we get the urge to say something every now and then . This is guided by our experiences in the past and mind filled with unnecessary things . Relationship built over years may just be blown away by a careless uncontrolled tongue. Let all thoughts swell up in your mind but don’t give free rein to tongue. Think twice before you speak. If in doubt , best policy is to keep quiet and wait for the right moment to speak right things.
