Thank you for such a deep question.
I would suggest that you should study the teachings of Samael Aun Weor. There is a great website where you can get all of the real ancient mystery and enlightenment teachings for free. (First time in history)

Daily mediation, prayer, and the study of Qabalah are the tools you need.
Also, it’s important to understand that real initiation comes from the inside. Nobody can make you enlightened through a ritual. They can only show you the direction. You need to do the work.
Every day is hard work on the path, but it’s 100% worth it.
