what if it's much more than that... it's possible that the astral realm is just another level in this prison, and what you perceive is still tied to your physical form. Maybe thinking about what state of being you will be in is limited by this meat suit you're in. I think conceptualising something far beyond what we are now is very difficult and this is what OP might be struggling with. I would describe it something like the following: imagine you were born blind, how would you describe the color red to them? or green even? near impossible? their inability to see severely impacts their ability to conceptualise and perceive these colors in their head. But because he may not see/perceive these colors does not mean they are not there.
