As far as I read,Mokusou in kendo is sitting in seiza,emty your mind and breathing properly.Talking about breathing properly,the manual say that we breath in by 3sec through nose,using our abs and hold the air in seika tanden for 2s,then release it through mouth for 10-15s.

I don't really get the part "breathin by using abs",are we going to sink our abs or enlarge it ? I ask my sensei and he say I shouldn't focus too much in that instead of empty my mind,just breath in by nose and out by mouth steadily.

Can someone explain this to me,please ?


P/s : I have another small question to ask : If a senior from another dojo come to practice at our dojo,where he should sit ?
