The mind is more comfortable in a landscaped park because it has been planned through thought; it has not grown organically. There is an order here that the mind can understand.
In the forest there is an incomprehensible order that to the mind looks like chaos. It is beyond the mental categories of good and bad. You cannot understand it through thought, but you can sense it when you let go of thought, become still and alert, and don’t try to understand or explain. Only then can you be aware of the sacredness of the forest.
As soon as you sense that hidden harmony, that sacredness, you realize you are not separate from it, and when you realize that, you become a conscious participant in it. In this way, nature can help you become realigned with the wholeness of life.
