Knowledge clears out all doubt
It is stated that “Not to know” is the biggest problem in life, because if we don’t know, we will spend our life with doubt in everything. On the contrary, if we know, all doubt is cleared. This reminds me of a story: an old man hid a coin in his hands and asked children if they want to know what in his hands. They said, “Yes, we do.” The old man said to them, “Bow to me then, I will show you.” All the children bowed to him. Then, he opened his hands and showed them. The old man held his hands and asked them again if they want to know what in his hands. They said, “Nope, we have already known it.” Therefore, knowledge will clear out all doubt.
