The thought that the entire responsibility of regulating and controlling our thoughts processes is within our hands, should constantly remain at the base of our mind. A provoking word spoken by some person, incites our anger and an event induces our sorrow. A movement of the eyelid arouses hatred, lust, love or joy. By this we become emotional and by emotions we get anger, fear, joy etc. Emotions are the result of our thoughts.
Thoughts are the source for emotions.
When we realize this, we can control ourselves. Generally we do not think like this. Suddenly something happens in the morning and our mood is spoiled. We fail to understand why we so readily get angry for everything or why we lose control over our emotions. That mood of anger and irritation fills our minds.
