In your practice, if
you want to make some effort, your effort should be directed to keeping your
posture right, or to have deep breathing, or to put some strength in your
tummy. This is all that you should do, but as you have experienced, to have
right posture, and to have right breathing is not different thing. It is the
same practice. -------------------------------------------------- Excerpt from Shunryu Suzuki lecture - 68-01-18 as found on shunryusuzuki.com. Edited by DC
