By "unselfish" we do not mean "generous", and you will never be asked for a donation by anyone in Wo'O's Table.
The essence of being unselfish is understanding that you are a part of something larger than yourself, something that you care about and that you devote your life to serving. That "something larger" can be "God's Creation" or your country or your race or humanity in general or the Earth. It can be whatever larger thing you care about and that you see yourself as a part of. If you have several larger things that you see yourself as a part of and that you live for, the one that takes precedence is the one that we are talking about.
