Here are a few words of wisdom which give me a deep impression:

"Man does not cease to play because he gets too old,
Man grows old because he ceases to play."  George Bernard Shaw

"We have enough religion to make us hate,
but not enough to make us love one another."  Jonathan Swift (1667 - 1745)

"I do feel that all experiences, even if they are painful and unwanted,
can be enriching.  I think unless you have known profound sadness,
you don't really know what profound happiness is. Perhaps you can't
have real joy and contentment unless you've known deep sadness too."
Princess Diana's mother, Francesi

"There is much tomfoolery in the practice of religion"   Jawaharlal Nehru
