Question: Why does a person return to his bad inclinations to a greater degree after transcending to a new spiritual level? Why is it impossible to be tested and to pass the next test like in university?
Answer: A person does not go back. He is given the next test—an addition to his egoism.
Even at school and in university, we study the same subjects for many years.
