>>514047611 search engines are being made shit. 2 most occult traditions are in absolute garbage shape. and 3 most modern practitioners rarely even measure up to those low bars so a lot of material is butchered tutorial level shit parroted by completely ignorant academics or genuine nutjobs playing with peanuts worth of power.
and even then actual internal alchemy practitioners are a rarity even among occultists and most will never escape the kanto or johto stages and those are more or less tutorial levels.
as reference this new gen represents an attainment only the masters of the most functional traditions will ever achieve in all likely hood its the stage after attaining the first dhyana which according to Buddhists means you only have to reincarnate three more times.
