It is a thrilling journey to set forth in the forest
and to experience your mood shifting from mind entangled problems to curiosity and pleasure. Joy, energy and great happiness arise, and then, when you are fully present, to connect with a tree that calls to you and to "meet" it.
Japanese scientists have been studying the physical effects of consciously being in trees (Forest Bathing) and have found that within a few minutes our immune function is increased, stress and blood pressure drop, mood and concentration improve and so much more. Check out this link for more.
To bring your attention to a stone, a tree, or an animal does not mean to think about it, but simply to perceive it, to hold it in your awareness. Something of its essence then transmits itself to you. You can sense how still it is, and in doing so the same stillness arises within you. You sense how deeply it rests in Being - completely at one with what it is and where it is. In realizing this, you too come to a place of rest deep within yourself.
