Don't thinking it is unnatural/can't exist is in my opinion a important. you do you get thinking about not thinking which is the kind of thinking that you do not want. (to share some experiences )
To get to someplace you have to go a way. I use another than you. I could write about it but that would be rather offtopic.
The poster asked about the nature of emptiness and specificly after the meaning of the sentence "Everything comes from the emptiness and returns to the emptiness".
quote:
It is experiential not analytical.
The emptiness it self is neither experiential nor analytical, it is just what it is. Your perception of it can be experiential or analytical, but that doesn't mean that other people aren't allowed to have another perception.
I would agree with you that the experiential side of your emptiness trainings is not the same as Tôheis, but that doesn't make the point that it is the same concept invalid.
