Magic Forums

Hello.First of English is not my first language.So,please cooperate.
So,I recently bought a book called Summoning Spirits: The Art of Magical Evocation
The exercises in the book are working wonderfully and I can clearly see the improvement in my abilities.Like improved mirror gazing.My abilities did improve at a rapid rate.The practical part is wonderful.
At the beginning the author tries to dispel some myths regarding evocation.Like how church portrayed it as evil and how god is really the source of magick.One of the myths he dispelled is about evocated spirits being parts of our subconscious.He talked about how arm chair theorists made it up and why it is wrong.And something and efficient cause and final cause and used it to explain how spirits are not part of human subconscious and how they are independent of human mind with their own intelligence and cause.
I did not find it satisfactory and now that is frustrating me.
I believe some people here really have experience with gods. So,if you can answer these questions satisfactorily,I can have my peace of mind back and I'll be very thankful.

1.Is astral plane just in our mind? or is it like people say...like our universe...Its own thing.Like they say every physical being has its astral counterpart.Like where my body is in physical world,my soul is present in astral plane simultaneously.

2.Are spirits I summon(like elementals,planetary spirits,angels,demons and many other) simply a part of my subconscious or are they independent intelligence's? Like a different being with its own thoughts and character?

3.Are god forms natural one's? When the author classified basic types of entities he classified Thoughtforms and Egregores as artificially created one's and all other spirit types as naturally existing one's.So,god forms are naturally existing one's? He warned to never evocate god forms as they are insanely powerful.Why is that? He is fine with me evocating angels and all others as I command them with divine authority.Why are god forms different?

4.So,spirit guides and all other spirit types and the astral plane are independent of humans?
