Life will certainly teach you, but at the cost of great suffering. And there is no guarantee you will be able to learn in a lifetime, because when your life teaches you then life has no conscious agenda to teach you. Life just operates on the principle of result of action. You do something foolish, you get hit in the teeth; that’s how life teaches you.
When there is a teacher, the teacher has a conscious agenda to uplift you. Life has no conscious agenda to uplift you. Life’s principle is: be wise, get rewarded; be stupid, and get kicked. That’s how life operates. So, life just does not want you to learn. Life does not want anything from you. Life is just like an input-output box—garbage in, garbage out.
Unfortunately, we are born with garbage and as garbage. Therefore, life will keep heaping more and more garbage over you.
