1) The soul and the body are different forms. While the body is visible and mortal, the soul is invisible and immortal. He suggests that although the body dies and decays, the soul continues to exist. I do believe there is life after death, everyone must eventually die, and it cannot be avoided. However, even though death is a fact of life, it is a topic that many people prefer not to talk about. This avoidance of discussion is usually due to the denial of one’s own death and the denial is usually due to fear. The fear is, for many people, a fear of the unknown. In my opinion i believe that when humans die, the body and the brain dies, but the mind still exists and it creates our afterlife according to our own beliefs and expectations. If a person believes there in nothing after death then there will not be a dream, it will be as if the person is asleep forever without dreaming.
2) Yes, I agree that the universe is purposeful. The purpose of the creation, every though you have is creating your tomorrow. The universe has mysterious ways of revolving what we do day by day. For example Karma: The sum of a person's actions in this and previous states of existence, viewed as deciding their fate in life.
3- Aristotle said: “Yet there is God, though not perhaps the simple and human god conceived by the forgivable anthropomorphism of the adolescent mind."
Aristotle represents God as self-conscious spirit. A rather mysterious spirit; for Aristotle God's never does anything; he has no desires, no will, no purpose; he is activity so pure that he never acts. He is absolutely perfect; therefore cannot desire anything; therefore He does nothing. His only occupation is to contemplate the essence of things; and since He himself is the essence of all things, the form of all forms, his sole employment is the contemplation of himself.
