Physical and Astral Realm Border identical or not?

[Mirador]

TruthSeeker,

What we call 'physical', 'spiritual', 'astral' are terms we use to describe aspects or features of the 'Known'. It's valid to say that all of these are superimposed one-on-top, or one-inside the other, There's only One realm, and we may choose to enclose each in one or a multitude of membranes, if it suits our fancy. Our description of the Cosmos is dependent of language, and all our descriptions can only be a metaphor for the Real thing.

Who knows if the Physical realm (cosmos) border ends at the exact same places and points in time as it's adjacent spritual and astral realms?

Are both realms, Physical and spirtual, enclosed by some bubbly membrane as one of the members on this web page has said?

What are everyone's theories and beliefs on this issue?
