Lol idk but Satan is a small piece of the puzzle. And the Supreme God is a much bigger piece. The supreme God created all the dimensions, and must of given form to every other deity. That's why there's like a million different Gods, and they are each just as relevant. Or they were at least.
So then if God is a much bigger piece, you haven't actually encountered Him yet in the astral space yet. In the astral space, God can very simply be described as a stop sign. Other entities don't have the power to stop anything you do. They can try to influence you, but free will is the same in the astral space. This may create struggle, but the Bible verses about temptations remain true.
"No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it." (1Corinthians 10:13).
"Let no one say when he is tempted, “I am being tempted by God,” for God cannot be tempted with evil, and he himself tempts no one." (James 1:13).
So, this is really a very simple way to tell who you are dealing with. God does not tempt us to sin. The Devil can't make you sin, so they give you choice, and hope that you will choose to sin and turn away from God. So if someone tries to give you a choice, or two options, that is suspicious; but it also might not be so obvious that this what is happening.
However, God is able to stop you. He doesn't need anyone's permission either. It won't be a discussion. He can just put a stop to things. Satan cannot do that. That is the difference between Satan, every other entity out there, and God in the astral plane.
It is possible to see none of these sorts of things when you astrally project, but this is how you would know what you were dealing with. Someone who comes from God can't disobey Him also. There are very easy ways to test who you are dealing with, but it is better to know how to do this before you try to do something like this.
I would obviously recommend not doing it at all, but if someone really wants to do this, then this is what I would recommend considering.
