The universe has been created with two faces. To get from one to another is a stage, and to get from one stage to another is a test. Now imagine a child sitting in the examination room. When the examination is placed in front of him he begins to cry; instead of solving problems on the test, he starts to complain and protest that he is being tested. The development and prosperity of human beings are not possible with an exquisite process. Gold becomes pure only after passing through a kiln process. If humankind had not undergone these kilns people today would be living in caves.
