Answer: There is an upper reality. If someone comprehends it, then it exists relative to him. If one doesn’t comprehend it, then it doesn’t exist for him.
Now we all feel the earthly reality in the same way because we are on the same egoistic level.
Question: On an altruistic level, will we also feel one reality or each will feel his own?
Answer: Together we will feel each other and one reality. Moreover, everyone will have their own reality, but they will all be similar.
