Stop loose talk
One of my spiritual guru said - "Hurting someone with words is like cutting a person's stomach with a saw without giving anesthesia". To make it worse, loose talk is like the arrow that left the bow. There is nothing that can be done to undo the damage. The only solution is - don’t let that arrow leave the bow.
​
A typical example for those having a job – Remember the situations where you sent out a nasty email to someone in a fit of rage OR after having a few drinks when your mental state is not in the right place. Once you come out of the rage OR you are more sober, you will regret sending the email. But that regret is useless and you have to do a lot of damage control to compensate for the damage. In spite of all that, 100% of the damage is not undone.
Similarly you would have said some harsh words to your loved ones when they "did not meet your expectations" and then repent most of your life thinking "I should not have said that..".
So, what's the solution. When you are in a rage OR in a disturbed situation, do not take any steps. Do not say anything. Just walk away from the situation and get back to the person/situation once you are in a better state of mind. This simple exercise will save a lot of embarrassing and painful memories in your life.
