"All living beings have the same basic wish to be happy and avoid suffering, but very few people understand the real causes of happiness and suffering. We generally believe that external conditions such as food, friends, cars, and money are the real causes of happiness, and as a result we devote nearly all our time and energy to acquiring these. Superficially it seems that these things make us happy, but if we look more deeply we shall see that they also bring us a lot of suffering and problems.

"Why is this? Happiness and suffering are states of mind, and so their main causes cannot be found outside the mind. The real source of happiness is inner peace. If our mind is peaceful, we shall be happy all the time, regardless of external conditions, but if it is disturbed or troubled in any way, we shall never be happy, no matter how good our external conditions may be. We can understand this through our own experience."
