If you young people who today belong to the first generation of the 21st century make an effort now, you may be able to create a happier, more peaceful world. But you can't take for granted that it will happen by itself, you'll need to take action.
Every single being, even those who are hostile to us, is just as afraid of suffering as we are, and seeks happiness in the same way we do. Every person has the same right as we do to be happy and not to suffer. So let's take care of others wholeheartedly, of both our friends and our enemies. This is the basis for true compassion.
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.
