The Imaginary Tree is divided into 2 parts:
Imaginary Space and Real Space.
Imaginary Space is non-physical and naturally the source of Imaginary Energy, whereas Real Space is what happens when the aforementioned energy moves throughout the tree and forms physical constructs. It’s only natural that Imaginary Energy is abstract because it’s the fundamental substance that creates the corporeal things—I never doubted this part.
Basically, the former is abstract space-time whereas the latter is concrete space-time. That’s all; it is not transcendent to it in the way you think, otherwise statements
like this wouldn’t exist.
