The 13 Doors, Mental bariers and gateways to knowlage Options

so i have been told by various spirits that there are 13 ish mental doors to unlock before you can be fully aware depending on the paths you take and the way you open the doors [ no im not totally clear on how it works or what it all means exactly lol] so far ive opened 3 the first 3 are wooden this was relatively easy, i did have some guidance and assistance. the 4th is the first of the stone doors and is proving rather more difficult to budge i know i need a key or something to roll it aside and i think the artwork on the front is a clue, maybe a piece of knowledge i need to understand before i can progress further.

my main question though is has anyone come across this idea of doors before ? if so where and any other info you have would be wonderful as Google is coming up dry for mental doors and gate ways like this.

thank you for reading.

@op there arent 13. doors. they lie and will have you.
revoke your spirits. never ask of them again.
why 13 doors? you are your own Self, and you are 1.
I know you wont follow my advice. Im 1 / 13
Say to them you are your own Self
I am that I am, be gone cruel visions of my past
I am that I am
I am that I am
My spirit, you are my greatest being
Help me now
My spirit
You are Strong
help me and revoke these bad spirits that haunt me
My spirit, you are alone that I am
Kill them and the evil they are
My spirit

Ask your spirit after you fall to restore you
Never seek power outside your SELF.
Your Self is Almighty, and it not blasphemic to say so
YOU ARE THE SPARK YOU HAVE IT ALL
AWAKEN IT
