No. You wrote more than that. ” The eye for example comes in contact with photons. But the tree is not made of photons.”
I have revised my reply above to include the whole statement. It did not explain where actual contact (phassa) is made. From your statement, someone could get the wrong idea that contact is with the eye with photons.
I have explained what happens with the photons.
– Nothing wrong in your statement per se. But it did not clarify what happens. I was trying to explain exactly what happens, and what is meant by “phassa”. I was just trying to help, not to criticize.
– By the way, when I write a comment, I am trying to explain things to the general audience. I try to provide a comprehensive picture, when possible.
P.S. Of course, a tree is not made of photons. But photons (light particles) need to bounce off a tree for the tree to be seen. That is why we cannot see trees (or anything else) at night. Again, this is a general clarification, and not to you, Tobias. You are an engineer, as I remember.
Tobias’ last question: “Also photons are made of the great elements, thus they are not vanna rupa but a mixture of apo, tejo, vayo, patavi, correct?”
Yes. That is correct.
