Truth and knowledge are not the same thing. There are many lectures on this site and elsewhere by Master Samael and instructors explaining pysychoanalytical meditation. However it is intuitive knowledge that we require in order to eliminate the ego. We can't do it with theoretical knowledge. There has to be Self Observation and Self Remembering.
We must know something for ourself first before we can think of becoming scientists of the soul. A good analogy can be found in modern science where mathematics has replaced natural science. This gives us science that is theoretically heavy and scientists who are erudite in matters far removed in time and space which they cannot verify in their own experience. Meanwhile, we are ignorant of matters that are right under our noses, foremost among these being our own psychology.
The Path is not a game where we collect all the pieces to win. There is a didactic within the consciousness that is not our responsibility. It is the responsibility of our Being and this is why we pray to our Diving Mother for elimination when we comprehend something about the ego. Our responsibility is to be diligent in our practice.
Luke 21:19
In your patience possess ye your souls.
