Eckhart Tolle

Nature can bring you to stillness. That is its gift to you. When you perceive and join with nature in the field of stillness, that field becomes permeated with your awareness. That is your gift to nature.

All things in nature are not only one with themselves but also one with the totality. They haven't removed themselves from the fabric of the whole by claiming a separate existence: "me" and the rest of the universe.
The contemplation of nature can free you of that "me," the great troublemaker.
