When doing anything, there are always parts that can be learned and things that cannot be learned. Some concepts involving ultimate concern, such as truth, goodness, and beauty, should be learned. However, there is no need to learn from other people's specific operating methods and external forms. Only by finding the hidden ideas behind the appearance, and finding the road to heaven and earth from behind the ideas, can we always have the inspiration for innovation and the opportunity to act. This is the power of insight.
