About Ki training,
I recommand you focus on how to control your breathing through it.
Not Ki itself.
I don't believe all of the concept 'Ki' is deceptive,
but not everything that it say literally is true.
We'd better try to find out behind its concept.
>I had a friend from Macau who teaches Tai-chi and asked him to give us a class of Ki training...
>Good! But I still seem to lack motivation to do it everyday, I just don't know what to feel and it discourages me.
