You are meant to judge physical reality. You are meant to realize that it is a materialization of your thoughts and feelings and images, that the inner self forms that world. In your terms, you cannot be allowed to go into other dimensions until you have learned the great power of your thoughts and subjective feelings.
SethThe basic idea of karma is not punishment. Karma presents the opportunity for development; to make use of opportunities that were not taken advantage of, to fill in gaps of ignorance, to enlarge understanding through experience, to do what should be done.
