Alain Is it necessary to do the grounding excercise when ever you do the Steam Release technique, the Wombing, or the Tractor Beam Technique? When i read the printed handout it doesn,t mention it, but i was wondering if it might improve the process

No, it is not necessary. That said being aware of the dynamics of a flow is useful and can augment the sense of the fields in such things as wombing.

Having an overall sense of numerous dynamics is good as long as it doesn't distract you from your major focus.
