Hi there:-) I was reading "The unfettered mind" the other day and one of the things Takuan Soho writes made me think about why we do Poomsae over and over again. It made perfect sense to me, so I thought I should share it with you here. As you know I think that Poomsa (among other things) display tactics and strategy, or principles through a collection of techniques in other words.
The Unfettered Mind by Takuan Soho page 11:
"Even though you know principle, you must make youself perfectly free in the use of technique"
