"This being human is a guest house.
Every morning a new arrival.
A joy, a depression, a meanness,
some momentary awareness comes
as an unexpected visitor.
Welcome and enter them all!
Even if they're a crowd of sorrows,
who violently sweep your house
empty of its furniture,
still, treat each guest honorably.
He may be clearing you out
for some new delight.
The dark thought, the shame, the malice.
meet them at the door laughing,
and invite them in.
Be grateful for whoever comes,
because each has been sent
as a guide from beyond."
(Mindfullness cog. therapy...(Segal, Williams, Teasdale, 2002)
...to take a stance of meeting each and every thought, feeling, or bodily sensation "at the door laughing" is radical. Acceptance means allowing or letting feelings (combined with thoughts) be and register their presence before deciding how to respond to them (true freedom according to me). It offsetts the tendency for our attention to be automatically "hijacked" by passing thoughts and moods. Most of the time, the effort we put onto our impulse to resist, avoid, or withdraw keeps us from seeing that an alternative approach is possible...
