Insight is the environment around the breath

As far as Buddha was concerned, at that point [of his enlightenment] it was
not the message but the implications that were more important. And as
followers of Buddha, we have this approach, which is the idea of
vipashyana, literally meaning "insight." Insight is relating not only with
what you see but also with the implications of it, the totality of the
space and objects around it. Breath is the object of meditation, but the
environment around the breath is also part of the meditative situation.
