Happiness arises as a result of different causes and conditions. If you harm someone out of anger, you may feel some superficial satisfaction, but deep down you know it was wrong. Your confidence will be undermined. However, if you have an altruistic attitude, you’ll feel comfortable and confident in the presence of others.
Dalai LamaEvery human action, whether it has become positive or negative, must depend on motivation.
Dalai LamaDepression seems to be related to fear, anger and frustration. When you're in a bad mood, even if you meet with your friends, you don't take pleasure in their company. But when you're in a good mood, even if things go wrong, you can cope with them without difficulty. This is why putting yourself in a good mood, making a point of developing a sense of loving kindness gives you greater inner strength.
