Meditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
You create your own universe as you go along. The stronger your imagination, the more variegated your universe. When you leave off dreaming, the universe ceases to exist.
The history of reform is always identical; it is the comparison of the idea with the fact. Our modes of living are not agreeable to our imagination. We suspect they are unworthy. We arraign our daily employments.
Our imagination is larger than the world around us; we go beyond our limits. This used to be called 'witchcraft,' but fortunately things have changed, otherwise we would both already have been burned at the stake. When they stopped burning women, science found an explanation for our behavior, normally referred to as 'female hysteria.' We don't get burned anymore, but it does cause problems, especially in the workplace. But don't worry, eventually they'll call it 'wisdom.'
Opinion involves belief (for without belief in what we opine we cannot have an opinion), and in the brutes though we often find imagination we never find belief.
