Universities should take their own courses, develop their careers and make money first!
Then I use my spare time to study these metaphysics. This thing really depends on understanding. Some people understand it after reading it, while others don't know how to say it!
I learned the theory of this thing very well at school, and after a few years of practice outside the society, I may become a master.
One more thing, many true masters of metaphysics don't make a living from it. Only in this way can things that are not interested be promoted in knowledge.
Besides, with the theory and foundation, it is enough to learn from the teacher. When you meet a master, you will learn something deeper.
