When life teaches you, 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, 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.
