I recently had a the pleasure to spend some time with Rob Nairn where
he explained a little bit of the tibetan buddhist theory of mind.
This set me thinking and I've come up with an interesting speculation
on how this maps to some recent theories on how our brains work.

When learning meditation, one of the fundamental things to learn is
not to attach. When doing virtually any other type of self discovery,
the importance of goals and outcomes are usually brought to
attention. So what to do? Set goals, attach and introduce unhappiness
or let go of everything, find a cave and be happy. Oops, even finding
a cave is a goal it seems! Slowly I'm learning that there is a subtle
third alternative.
