14.4 "...your fifth dimension ..."

[Nicholas]

 It is like the "broadcasting zone". A radio tower of sorts.

Very, very similar to how I perceive it too. It's like the saying when something 'flies over our heads'. Metaphysically I think it literally does if we are not vibrating at the appropriate height, if we were to assume that the radio mast were transmitting in a lateral fashion. I used to think of it as concept clouds. Physically speaking we have planes to reach such a height, but mentally we only need to develop our self awareness and behaviour patterns to reach the appropriate altitude.

As an aside I have been recently wondering at what point does our intuition play a role? Is it green ray activation, blue or indigo? Or is it available without any energy centre activation required? I suppose that deserves a speculative thread of it's own!  

 Since they qualified the statement with "your fifth dimension" rather than just "the fifth dimension" I surmise they were referring to our 5th subdensity. 

That supposition would be totally consistent with the many times that Ra said "your people", or "what you call" usage.
