Dean's question: Please explain differences between astral, super-astral and spiritual? Are these separate locations or deeper existences within the same location?

These are separate locations or deeper existences which are accessed from the same location, which is the subtle body. Even though the subtle body is using a low frequency usually, it is still the place from which to make the leap to higher dimensions. As it is now, we have no other place from which to act.

There are several astral planes beginning with the one which is adjacent to this physical world. When we meet deceased people in dreams and when we meet living persons in dreams, usually, that is the lowest of the astral planes.

Higher astral places are there. That is where we meet people who are not interested in physical existence. Higher than that is the super-astral places which in reference to what we experience now is heaven.

However, beyond that is a place where there is no subtle body like the ones, we use now, but where there is existence and where the self itself is the body, rather than the self using a body as we do now.

Consider if your personality itself was a body instead of your personality using a body to express itself. Like for instance if you take birth as a puppy. It will still be the same personality but it will be constrained by that canine form. But if the personality itself was a body, then there would be no need for a physical or other subtle body. That would be a spiritual form.
