Eckhart Tolle

People tend to dwell more on negative things than on good things. So the mind then becomes obsessed with negative things, with judgments, guilt and anxiety produced by thoughts about the future and so on.

Spirituality does two things for you. One, you are forced to become more selfless, two, you trust to providence. The opposite of a spiritual man is a materialist. If I was a materialist I would be making lots of money doing endorsements, doing cricket commentary. I have no interest in that.
