I have been in Kew Gardens recently and was overwhelmed by the old trees who invited me under there branch umbrella. Particularly one of them drew my attention being huge in size and tall. It must have been over 60 years old. I gave him some Reiki and the tree energy is very very deep and calm.
I needed to keep quite a distance to allow the aura of the tree to enjoy the energy and I could feel a true connection specifically in the area of the end of the spine. Trees are a fabulous teacher for us. They put their roots deep in the ground and go deeper and deeper towards the earth while in the same time growing higher and higher to the sky.
My learning from this was that you need to be rooted to be connected to the sky, which I translate in you need to be rooted on earth to be able to enjoy the spiritual realms. If you are not rooted you easily can be lost in those spiritual realms as your energy system can’t translate and integrate the energy in the here and now.
