Time and the Dissolution of the Ego

Upon speaking with a friend about what I consider our true state of being, I stated that our true Being was perfect, as it emanates, reflects, and is in essence directly connected to God. I have begun to recognize that the ego, in states of dysfunction especially, is not the true Self. My friend asked, and I had no answer, that if this Being or Self is perfect, why doesn’t it shine through/overpower/ or transcend the ego immediately? Why must we bear this outer material shell with the mind’s accompanying trivialities and dysfunctions? Why doesn’t Being immediately or quickly dissolve ego? I feel the purpose of existence in this plane is to learn and grow, but that in itself doesn’t answer this question. I would love to hear your response. I have read several of your books, and we both got to hear you speak. We would both truly appreciate your insight.
