Re: "stance of heaven (and earth)" and IS
On internal power, it is in this moment in you now. never in the future or past, its the eternal now, no voice to see no hert to hear. Heaven is right where you are standing and that is the place to train.
go through the small "gap". you creat space in your mind by "seeing space" this frees your mind from thought so your actions are not dominated by your thought, you access the internal power of you now, in this moment.
Your actions have no trace of thought or emotion "i hate this technique/person/situation so I will ppower throught it to get away from it"
if you cant disidentify with your mind and see who you really are everything else will be for naught. IMHHO.
