My wife and I tried to push the tree back into a fully upright position, but we were unable to move the tree one inch. I have attempted to send Qi to the tree. The older the tree, the stronger the energy it will have, provided that the tree is healthy. An uprooted oak tree is dying. You can be compassionate to the dying tree, but it is not your responsibility to take care of the tree.
Trees are generally more in tune with nature than people.
Send as much energy to the tree as you can afford, but try not to interfere with its natural path. For ten years I have practiced sending flakes of gold out of my chest to warm others when I meet them. After reading your book, it appears I have been dong a form of Qi movement. What you are doing before going to bed is fine. You can, of course expand your practice further.
