Self-knowledge is the foundation of life. Without it life will be in turmoil. If there is no self-knowledge we are bound to act from a psychological center woven by thought and so limited and results in limited action if we act from that center and so it leaves an impression called which knocks our door for resolution. This limited action results in experience of non-understanding. Such collection of experiences which cause problems is called ego and at present we are functioning from which adds further experiences. Experiences and so ego is dead past. We are facing living present moment wearing glasses of dead past. So we are just perpetuating the past by incomplete action that has roots in past, tradition. This calamity happens because we are using thought to solve both physical and psychological problems. Psychological problems are created by thought and how can you hope resolution of psychological problems by thought? S o thought has no place in problems of psychological arena .Man has not solved psychological problems for the past 40,000 years of existence on earth. Though man is able to technological advance in a surprising for which his efficient thought is the cause but lack of resolving psychological problems is due to use of thought in resolving psychological problems thus complicating existing psychological problem because thought has no role in resolution of psychological problem and thought is the causative factor for producing psychological problem. So if thought subsides when we face a psychological problem we develop insight which sees the whole net work of psychological and keeps away from it if it found as a dangerous precipice. So psychological learning is through "insight" only where as physical learning of through "doing" which involves time. So physical learning involves thought and time. Psychological learning does not require time because here "Perception" is action. So seeing old pundit Adi Sankara out of compassion gave message to him the importance of self knowledge in life.
