Spoken by Supreme Master Ching Hai,
Singapore, September 26, 1994 (Originally in English)

Every corner of the Earth affects the whole planet. You know it very well, because recently the fire in Indonesia affected the whole of Singapore, Malaysia and the neighboring countries. So actually, from this kind of natural lesson, we can tell that one person or one place on this planet affects another part of our planet.

Therefore, if you, yourself-your heart, your mind, your speech and your actions-are pure, how beneficial can it be to this planet? This is very logical; we have no need to argue or demonstrate.
