I had a question on the ending exercise. It says in the manual that the time to do it is 10 mins and the time on the video tape is ten minutes. Master Lin only goes through the exercise once and it's definately not 10 mins long.

Should this exercise be practiced only once at the end of the exercises? Can it be done over and over for 10 minutes? Can this exercise be practiced all by itself with benefits?

Thanks!
