There's a lot to be said about breathing. We take it for granted at times - hell we don't even have to think about it and it happens.
We type, chop wood, replaster the ceiling for the third time and throughout it all - we're breathing.
I guess that's why the teachers, the yogis ask us to focus on it. Feel it - in and out. It reminds us that it is happening now and now is where we should be.
Lovely poem, Thom!
