QUESTION (resumed) :
Taking the air to the abdomen?
QUESTION (original) :
Please, it is not clear to me if when I breathe in I must take the air to the abdomen or if I do that when I breath out. In 'Zen in the Art of Archery' they teach the author in a different way from the one I was taught in the dojo of Buenos Aires. ALSO ON THE WEB OF THE URUGUAYAN BUDDHIST ASSOCIATION, THERE IS A DRAWING WHERE THE ABDOMEN 'SWELLS' WHEN BREATHING IN AND DEFLATES WHEN BREATHING OUT. In the dojo of Buenos Aires is exactly the contrary. Thanks, I hope you can shed some light on this.
ANSWER :
The Zen breathing is the opposite, this is you expand your abdomen when breathing out.
KOSEN!
