Well I wouldn´t call astral projecting a science anyway.
It´s more of an art wouldn´t you agree?
So please go ahead and call it pseudo science or even anti-science.
Could science be considered an art?
Suppose it could. Dadaistic Science. Now that´s something right there
Spiritual exploration and experimentation is a science or school for the spiritualist. The cause and effect is carefully mapped by the student.
In time the student realises truly the meaning of the map not being the territory. Then one drops out and laughs at all confused dogma.
Then you awake and life is just a dream.
All students of any school reaches this point. Studying is not doing.
The essence is doing and being. Whether something is valid is up to the participant. Do or don´t. Optional.
Reality is vapor so why question any form it takes?
