Any conclusion or hypothesis - Individualism or Collectivism, Capitalism or Socialism or Communism, Reincarnation, etc. - is a belief. By accepting a belief, you exclude all other forms of thinking. Belief in God does not mean understanding God. A mind tethered to a belief, hypothesis or conclusion - whether based on its own experience or the experience of others - cannot go far; it is not free but conditioned. Therefore, belief is a hindrance to understanding.
