Dear Etoile
Absolutely go with, and implicitly trust the energy and Master Lin - several months ago I experienced some very similar and extremely powerful movements like you are now going through - and I had a very weak, sore back as well. It sometimes is difficult and even scary to believe that the body is capable of holding the sometimes contortion like positions that the energy puts us into but believe me, it and Master Lin know precisely what they are doing!
We are very privileged to be students of Master Lin and I for one am eternally grateful.
Warm regards
Jetay
