Metaphysics is the branch of philosophy that studies the ultimate nature of reality or existence. Here are some of the questions that Metaphysics primarily deals with:  What is reality?  What is the ultimately real?  What is the nature of the ultimate reality?  Is it one thing or is it many different things?  Can reality be grasped by the senses, or it is transcendent?  What makes reality different from a mere appearance?  What is mind, and what is its relation to the body?  Is there a cause and effect relationship between reality and appearance?  Does God exist, and if so, can we prove it?  Are human actions free, or predetermined by a supernatural force?  What is human being? A thinking mind? A perishable body? Or a combination of both?  What is time?  What is the meaning of life?
