You’re probably going to need to either draw into yourself, or find a way to link up with, literal godlike power for that kind of transfiguration, now you know this obviously but I’m being technical because it’s a massive task to undertake.
Because of this, first, I’m going to ask if the reason you want this can be acheived by a simpler method, for example if you want to become a leader and prophet, there may be faster ways.
Second I guess is to suggest you focus on energy work, drawing as much energy into yourself as possible, and also using it, regulkarly pushing yourself with magickal endeavours, to develop your psychic muscles and become as strong as possible.
It’s one heck of a miracle to accomplish and on the one hand, you may be naturally gifted, which means the desire is the natural knowledge in you seeking expression, on the other hand you may have to work quite hard!
Can you get a reading done to investigate whether this is going to be easy for you? I’m going to link below to a method of divination you can use, it has everything you need to get started, but don’t let just one method decide things for you, and I do advise trying to get some other input, maybe a Tarot reading or something.
The next thing I advise is getting a spirit mentor, I don’t know if you’re okay working with demons, some really powerful spirit who will help coach you and guide you, maybe a being like Azazel or one of the other demonic Kings.
This is a safe method of divination that has a legal download of the Oracle Book and my notes on how to adapt the questions:
