One day, the Buddha felt that his heart was in great confusion. He retired to the forest and fell to the ground at the roots of a tree.
An elephant approached the Buddha and said that it was unpleasant for him to see him despondent. Buddha was in a state of confusion, so he went back to the beginning, went back to where he came from, to find the answer.
So when you get into a dead end, go back to the beginning and find your way.
