The more adept we become at cultivating an altruistic attitude, the happier we will feel and the more comfortable will be the atmosphere around us. But if our emotions fluctuate wildly and we easily give in to hatred and jealousy, even our friends will avoid us. So even for people with no spiritual beliefs, it is important to have a peaceful mind.

Silence is sometimes the best answer

...there is an intense delight in abandoning faulty states of mind and in cultivating helpful ones in meditation.

From a Buddhist point of view, the actual experience of death is very important. Although how or where we will be reborn is generally dependent on karmic forces, our state of mind at the time of death can influence the quality of our next rebirth. So at the moment of death, in spite of the great variety of karmas we have accumulated, if we make a special effort to generate a virtuous state of mind, we may strengthen and activate a virtuous karma, and so bring about a happy rebirth.

The quality of everything we do: our physical actions, our verbal actions, and even our mental actions, depends on our motivation. That's why it's important for us to examine our motivation in our day to day life. If we cultivate respect for others and our motivation is sincere, if we develop a genuine concern for others’ well-being, then all our actions will be positive.

I think in many ways narrow minded-attitudes lead to extreme thinking.

Happiness mainly comes from our own attitude, rather than from external factors.
