To make a deep mental path, we think over and over the kind of thoughts we wish to dominate our lives.
~ Henry David Thoreau
It is only your lack of awareness and your grasping that make thoughts seem to have some kind of reality. If thoughts had any inherent existence in the absolute nature of mind, they should at least have a form, or be located somewhere. But there is nothing.
~ Dilgo Khyentse Rinpoche
