Robert Monroe quotes:

Fear is the great barrier to human growth.

The depth of learning is in direct relation to the intensity of the experience.

The most difficult mental process of all is to consider objectively any concept which, if accepted as fact, will toss into discard a lifetime of training and experience.

Always know and remember that you are more than your physical body.

Don't get addicted to being human. This is only temporary.

The greatest illusion is that mankind has limitations.

There is no beginning. There is no end. There is only change.
