Dalai Lama says,

"It is clear that inner peace is the principal cause of happiness. We can observe this in our daily lives. On days when we are calm and happy, even if difficulties arise or we fall victim to a mishap, we take it well, it doesn’t bother us unduly. But on days when we feel sad or have lost our usual calmness, the least little annoyance will take on enormous proportions and be deeply upsetting to us."

"The key to genuine happiness is in our hands. To think this way is to discover the essential values of kindness, brotherly love and altruism. The more clearly we see the benefits of these values, the more we will seek to reject anything that opposes them; in this way we will be able to bring about inner transformation."

"When we wish and seek to help others, our attitude is more positive and relationships become easier. We are less afraid and have less anxiety. Otherwise we remain shy and hesitant, and feel the need to take a thousand precautions before we approach people. When our intentions are good, we have greater self-confidence and are stronger. This is how we learn to understand how precious and valuable kindness is."
