Great suggestions from both, thanks.
I will try grounding in mother earth before I start my healings to see if it will help. And concentrate on the heart center after for extra support.
I find that during my healing session with animals I get 'messages' as to what is causing the blockage. That distracts me and I forget to concentrate on the energy coming in from the universe and through my body. Do I need to focus on the energy flow all the time or will it continue until I am done with the session?
