Providing knowledge on Facebook has now become a habit for many. A man posts great wisdom every day—he writes long statuses about morality, humanity, and philosophy of life. One day, he proudly told his mother, “Mom, I am providing knowledge to people, everyone listens to me.” His mother smiled and said calmly, “Dad, before teaching others, it is important to apply that knowledge in your own life.” The boy remained silent for a while. He understood that it is important to express knowledge not only in words but also in deeds. From then on, he started trying to correct his behavior. True knowledge is valuable only when it is reflected in life.
