“This new meta-system is very much in favor of the self, but a self that is based on a proper sense of dignity, not on an inflated ego. A person who dare not admit he is wrong inflates his ego but weakens his self.”

It’s not enough to rage against the lie.. you’ve got to replace it with the truth.

The awful thing is that you can never be aware of what you are not aware of.

The quality of our thinking will determine the quality of our future.

Mock the devil, and he will flee from thee.

Sometimes the situation is only a problem because it is looked at in a certain subjective, negative, ungrateful way.
