Planes instead of Densities

[caycegal]

Trying to understand the use of the word density. Ra seems to imply or outright state that higher consciousness is more dense but I always think of higher beings as light and ethereal.

More dense in terms of consciousness, less dense in terms of matter.  There is an inverse relationship between the two.  In the higher densities there is a more concentrated presence of thought, whereas on the lower densities the consciousness is more ephemeral and insubstantial.

Thanks.  I still have a question about "more concentrated presence of thought" because most spiritual teachers say we must control or stop our "thoughts" in order to align with higher spiritual vibration.  I believe there must be different uses of the work "thought" and also I wonder about whether sometimes people use the word "thought" when they mean something closer to "consciousness" or awareness.
