What does it mean when the yoga teacher says, "BREATHE"?

What does it mean when the yoga teacher says "BREATHE"?  Is it a command to inhale?  Is it a command to exhale?  Is it a reminder to not hold the breath?  Is it a cue to direct the idea of breath energy into the body? My answer?  When I say it, my intention is to help the student remember not to hold the breath and to synthesize body-mind, let it swirl together.  I hope it does not come across as a command to inhale or exhale.  And, that said, if you find yourself inhaling when the teacher says, "breath" try the opposite by exhaling when the teacher says breath.  Most people don't do this.  The exhale is a beautiful way to unravel tension and anxiety.  So, sort of flip your mind around and see the breath as starting with the exhale.  At the very least it is useful mental gymnastics.

I think it is a worthy question to ask any yoga teacher.  What do they mean when they say "breath..."?
