I've seen that phrase or something like it periodically. What is it? How do you do it? Also, would this enable me to render an image with a ground shadow, and then render it again with a background behind it?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
