Willpower is nothing but willingness to do.
Move from the known to the unknown.
True concentration is an unbroken thread of awareness.
If you have the right mind, your body can do anything.
We are a little piece of continual change, looking at an infinite quantity of continual change.
As long as the body is not in perfect health, you think about it, and that prevents you from thinking of the mind. The sound mind is a sound body.
