“Seth material” search engine (Jane Roberts)

The awareness is focused along certain lines. The tree lives through its inner senses, experiencing many sensations and reacting to many stimuli of which you are unaware. Minute earth tremors, even the motion of small ants about its lower trunk — these are recognized and experienced. Such invisibilities as humidity, radioactivity and all electrical values are felt as quite real things to your tree.

A tree knows a human being also … by the weight of a boy upon its branches … by the vibrations in the air as adults pass, which hit the tree’s trunk at varying distances, and even by voices. You must remember what I said earlier about mental enzymes and my remark that color can sometimes be heard … The tree recognizes a human being, though it does not see the human being in your terms. It does not build up the image of a man, but it builds up a composite sensation which represents, say, a given individual. And the tree will recognize the same man who passes it by each day.

As your own body senses temperature changes, it also senses the psychic charge, not only of other individuals, but of plant and vegetative matter. Your tree builds up a composite of sensations of this sort, sensing not the physical dimensions of a material object, whatever it is, but the vital psychic formation within and about it.
