In my opinion, I think it may be a good start to write down your spiritual experiences (things that changed your worldview, enhanced your morals, and things you care about), core values (what's important to you that won't budge on), and even your definition of life and death.
Maybe try it the other way around. Build up what you already know so when you read books, you're agreeing with those that match your experiences not just your interests.
As for type of books, I don't know. I haven't looked into esoteric books or anything like that. Mostly books on ancestral veneration, personal testimonies and stories on how people got to know their families, and people's diaries and things like that-because they are closer to my experiences.
Long short story
Im a musician by nature
I started to do music production when i was 12
Im still on the way and working on it.
I diagnosed with a epilepsy at the month of 3
(family told me that now)
I was on some toxic medicines until age of12 that my epilepsy gets better but at the age of 17 i was diagnosed with another shape of the epilepsy.
Which it was triggered by mental traumas and my ignorance pov that i mentioned. And whole seeking enlightenment things started from that point.
That i was loosing any sense of connection to any reality.!
That was nice 7 years of all pain and hospitalizations episodes and my mom nursing me.
That leads me to detox from all of the big pharmaceutical experimental mouse...
I got in the battle with the epilepsy and series of mental illness at the same time with consciousness expanding experiences
Meditation
Reading
Psychedelic experiences
For now my epilepsy is gone for good and thats not the point of my post anyway
But
It was an eye opening experience for me really in a negative karmic way
I want to know
If im doing the same mistakes i did in a previous birth before this one im now
How and what will happens to me when i complete this birth?
Honestly i know that where i was in my previous life
For thislife i got an life in a 5th world ****hole
With low quality of everything.
I don't have and can't wait to get any migration dreams to get fulfilled
System does not let me get out my trash country for good
So i count it as a bad karma that needs to hurt me
Anyway
Im really bothering and trying do something with my life but im a 23 old stay home son
Unemployed by my will
(i will not be another brick in the wall)
Still sitting and waiting for someone to charge my credit card for living
I stopped my music practices for nearly a 2months
All i do is sleeping and reading occult books
Im planning to this for next decade of my life
Until i get some where else as a refuge
Cause i don't care about anything i mean anything except me and my flirting occult e-book library ive collected
