Hello Siti
You are getting close to understanding VedAnta! This is exactly how the ancient Rshi (Seers) and their disciples conversed - the way you and fool are conversing, and this is the recommended route to understand the truth by questioning everything. Then the disciple is at a mature stage and goes of to contemplate on their own.
But if that is how consciousness works then none of these are 'persons' and neither are humans - so like I said earlier, under that scenario, nothing is subjective because there are no subjects
1. It is correct that none of these visible beings (plants, bees, animals, humans) are persons
in the absolute sense / at the absolute level. However, by calling the plant a person for a moment, you were right from the perspective of the individual plant. This is the illusory relative "i" that the plant thinks it is.
*Dr. Subhash Chandra Bose showed that plants have feelings, and the feelings are behind at least a few of the reactions if not all of them. This is why plants flourish when you nurture them with love, and SC Bose talked to his plants to prove they grew healthier, greener, bloomed more..
- only objects being acted upon 'at a distance' by spooky consciousness.
2. This "spooky consciousness at a distance" is the real Fundamental Universal Consciousness -
[param]AtmA, [para]Brahma[n'], which is the real upper-case "I" , the real One who is aware of Itself , and the projections dancing on its original fabric of existence are appearances, illusions, derived, transient, and not fundamental, hence have no absolute existence.
And I can't disprove that - but it seems to me far less likely than the idea that a cockroach is, in some sense, a 'person' and sees the world from a personal 'cockroach' point of view.
3. And this is the illusory small , lower-case i which is the local-ego which erroneously things it is the DOER. It thinks it is driving the actions and all. Takes credit and blames the objective puppets including itself.
Vedanta says that the upper-case spooky I is real, and the lower-case local-ego-i is the meddling [illusory] entity that causes all problems and illusions. Shri Shri Ravi Shankar compared the individual ego-i to credit card or money. Just keep it in the pocket, don't spend it, but don't try too hard to erase its existence or it will raise its head again. The local-individual-ego does not know there is a much bigger I behind the scenes.
