You are definitely right about "Life not having manuals". Without proper guidance, a long and painful road of trial and error lies ahead of us. We make mistakes and get hurt and then learn. As Edison said that the mistakes are merely leaning a way of how Not to do something. So by elimination you can arrive at the right answer.
But if the guidance of a teacher is there than the chances to avoid the unnecessary pain are increased and a person can find the lessons of life at the hands of his teacher, rather than at the feet of the world.
Another brilliant one. Yes, when we have someone who has passed through that same route and they leaned to pass the message across to us by teaching us the way to go, it saves us a painful walk and make our journey easier. Gracias brother. Love this too.
