When you are discontent, you always want more, more, more. Your desire can never be satisfied. But when you practice contentment, you can say to yourself, 'Oh yes - I already have everything that I really need.'

As human beings we each have a responsibility to care for humanity. Expressing concern for others brings inner strength and deep satisfaction. As social animals, human beings need friendship, but friendship doesn't come from wealth and power, but from showing compassion and concern for others.

Although you can find certain differences among the Buddhist philosophical schools about how the universe came into being, the basic common question addressed is how the two fundamental principles-external matter and internal mind or consciousness-although distinct, affect one another. External causes and conditions are responsible for certain of our experiences of happiness and suffering. Yet we find that it is principally our own feelings, our thoughts and our emotions, that really determine whether we are going to suffer or be happy.

Values are related to our emotions, just as we practice physical hygiene to preserve our physical health, we need to observe emotional hygiene to preserve a healthy mind and attitudes.

Even within one person, yesterday and today, there are differences. We must look at a deeper level.

We need to make material progress, but we need inner development too ... remember that the real development we seek is not in the buildings but in our hearts and minds.

Scientists may study mainly matter but they cannot ignore the human mind, or consciousness: spiritual practitioners may be engaging mainly in developing the mind but they cannot completely ignore their physical needs. It is for this reason that I have always stressed the importance of combining both mental and the material approach to achieving happiness for humankind.
