Observe carefully, one phenomenon, that of finding relief in being in nature, arises from sensory perception, the other, that relating to the trophic relationships between organisms, arises from the thoughts of your mind, not from your direct perception.
In you, as well as in nature, in the relationship between your cells, there are phenomena of apoptosis, as well as the elimination of cell groups at the expense of other groups, phenomena necessary for the survival of your body: this is usually not perceived as a problem, because you do not identify with individual cells, but with the organism as a whole.
Likewise, your view of nature can change, if you consider individuals of every species - who like any individual are doomed to cease, to die, in one way or another - or the drive produced by these relationships, which it is the one that allowed, through the dance of life and death, the appearance and evolution of the single species and, consequently, of the beauty that you can perceive in natural places.
So, the best way to relate with natural areas is to communicate with nature, of which you yourself are a part, using its language, which is different from that of words-and-thoughts.
It is enough to immerse yourself in what you are feeling in the present moment, look around until you discover something, a plant, an animal, a ray of light, a smell, a stone, a color, to which you are naturally attracted.
Approach it, always observing whether the sensation of attraction continues or disappears; if it disappears, look for something else, if it continues, mentally ask permission to get in touch with what attracted you.
If the attraction persists, after your request, it means that in that moment, through the direct perception of that attraction, “you” and “nature” return to being a unity, and that flow of perception has the possibility to produce a real mental and also physical regeneration, like the water of a pond which, suddenly, returns to be part of a stream and, as it flows, regains its original nature.
