One of the best biggest kick in my ass I got and really challenged the ego dissolution process I'm going through was by slightly realizing the deep truth of what an alchimist friend told me back in 2004: TOE standing for Theory Of Everything.
This has to do with non-duality awareness along with realizing any path or system will take us ultimately to self-realization. Any method will just provide a purification vehicle so one can jump safely into non-duality awareness while still living on earth.
The safety comes from a mixture of correct speed and karma dissolving efficiency for a given individual along with being blessed to attract the best method for us which might not be the best method for someone else.
The major problem is attaching to the awakening method which is just a story telling: the Mind trying to describe the Nature of the Mind experience. Ego trying to describe the method to dissolve ego which is a trap preventing Self-Realization. A catch 22 situation that only a few authentic masters have resolved.
For example, authentic shamanism is just an anthropomorphizing of the experience and one should be careful to first fully integrate the culture who create this cosmology (i.e. Ayahuasca and serpents are both commonly found in amazonia but not in cities) otherwise this might become a hell or a quick path to a mental hospital.
