Delusion is like a person in a dream

Awakening to reality is awakening to your own true nature. If you try to discover reality outside your own mind, you are simply adding delusion to delusion. Delusion is like a person in a dream thinking they are separate from everything else in the dream. The dream person, the dream world, and all the things in the dream are nothing but the one mind of the dreamer. If the dream person realizes that he or she is actually dreaming, they instantly realize that everything they encounter in the dream is nothing other than their own mind.
