Anyone who would use religion as their reason to cause unhappiness to another is guilty of a great sin. 

These sins are committed first against their children. They have learned nothing from their faiths. The extremists of both Christianity and Islam, for example, follow lives of violent repudiation of the beliefs of their own religions.

~ Robert Ebert, while commenting on Christopher Hitchens' book on Religion.
When you are content to be simply yourself and don't compare or compete, everybody will respect you.

~ Lao Tzu
