Thought is the most surface level of intelligence. What happens in one DNA molecule is a billion times more complex than your thought.

No one can cause mental pain to you. It is you - in reaction to something that happens around you.

Thinking is just a recycling of data that you have gathered in the past.

Human beings suffer their own memory and imagination; that is they suffer that which does not exist.

The intellect is a reasonably sharp knife. If you do not know how to hold it, you keep cutting yourself.
