The emergence of thought is the root of all mischief
“If a man considers he is born he cannot avoid the fear of death. Let him find out if he has been born or if the Self has any birth. He will discover that the Self always exists, that the body which is born resolves itself into thought and that the emergence of thought is the root of all mischief. Find wherefrom thoughts emerge. Then you will abide in the ever-present inmost Self and be free from the idea of birth or the fear of death.”
-from Talk 80 (Ramana Maharshi)
