The Universe does not cause pain, it causes experience. You cannot know happiness if you do not know pain. You cannot learn if you do not have experience. You cannot be compassionate if you do not have experience. You cannot love if you do not have experience. Pain is part of the journey of life. Blessed are those who have ever known any kind of pain or suffering for they will discover true happiness later. Experience allows us to really appreciate all the positive things in our life, and helps us to grow as humans and spiritual beings.
