Answer: Then a person would be an eternal beast, which we call an angel. In order to attain the upper level by himself, a person has to suffer.
Answer: No, he cannot. But the suffering can be different. There may be pangs of love. As the saying goes,”I have loved and suffered,” for example, I have loved money and suffered from the lack of it.
Here, on the other hand, you love comprehension, attaining eternity, perfection, and you want it to be absolute and objective. It isn’t as if you swallow some drug and feel good, but you have developed these feelings internally, these vessels by which you find out that you are really in a state of eternity and perfection.
