Yes.
Viv you say " so far this is just like a metaphor for either being alive or dont know"
I be honest with you, i dont know what a " metaphor" is. I mean the word is new to me. I could look it up in the dictionary, but its just a word.
So lets talk words:-
I am talking about " inner spirit".
writing requires disipline of thought and you want such thoughts to be expressed logically. But spirit is a chaos of sensibilities, feelings and thoughts. So future existence is " i will" " i shall" . It is the difference between " i dream". It can never die because it only exists in future existence. So if rocks and plants have chas of sensibilities, feelings and thoughts then i am saying they have future existence.
But i wasnt saying that.
And how can people die, if death is non existence? well i cant answer that because i have only known future existence. I guess you will say its for another topic. But what is death? You see to answer your question " what is spirit exactly" i think needs more questions.
As for me unlike rocks i can smell, tremble at the thought of dying in flames ( as my dear friend did) but i cant measure the depth of this "worlds spirit" .But i am alive and well all the same. To me thats " spirit". Future existence. As for my dear friend i think he has no future existence.
