Random Ra Material Questions

[andreazzi]

greetings, earthlings!

anyone care to explain Ra's definition of "inner planes" in this answer:

63.26 ▶ Questioner: Could you describe the difference that you are speaking of with respect to time/space and space/time?
Ra: I am Ra. For the sake of your understanding we will use the working definition of inner planes. There is a great deal of subtlety invested in this sound vibration complex, but it, by itself, will perhaps fulfill your present need.

I am really dedicated to the understandig of this critical concept of space/time and time/space. This is the most direct question Don asks about this concept that I could find in the material, but Ra clearly uses Don's concept of Inner planes to explain it, but it doesn't mean much to me...
