Here is another quote, saying it like it is, from the “Buddha Brain” by Rick Hanson, my “yoga grad school” assigned reading:

There you are, following a presentation at work, running an errand, or meditating, and suddenly your mind is a thousand miles away, caught up in a mini-movie.  But it’s only in the present moment that we find real happiness, love, or wisdom.
