The Astral body

Firstly, most people do not have an astral body.

Only a human has bodies; the "intellectual animal" has no bodies. That he has a "lunar astral body" is not so. The "intellectual animal" the only thing that he has inside are demons; It's a lot of devils, but it doesn't have more. When one says: "go out in the astral body", one speaks in a conventional way. They are the “I’s”, which penetrate and interpenetrate each other. The essence goes there bottled and can escape and go out and travel and get to know the astral world (to a certain point; not much, but to a certain point). What I said in one of my books about lunar bodies, I was referring to the egos and the three main demons that everyone carries inside, which are the demon of desire, the demon of the mind and the demon of evil will, which they act as astral, mental and causal, but they are nothing but demons.

So, practically, the "intellectual animal" does not have any kind of bodies: neither solar, nor lunar, nor anything; It's a bunch of devils that you have to turn to dust, so that the consciousness remains free and can see, hear, touch or palpate the great realities of the universe... https://glorian.org/learn/courses-and-lectures/lectures-by-samael-aun-weor/how-to-develop-ourselves-into-a-complete-human-being-and-eliminate-our-defects

Secondly, your astral form (whether solar or lunar) is the vehicle of your emotions and your connection to the emotional dimension of nature. It resides wherever your emotional awareness is. If you are aware in the present moment, then your astral form is here and now. If you are daydreaming, then your attention is using your astral form in the fifth dimension to project its dream there.
