Rejoice in complying with the way of heaven and recognize the limitations set by the mandate of heaven. This concept originates from The Book of Changes. The way of heaven regulates human affairs and its mandate defines the limit of human power. This is beyond human capacity to change and must be faced with calm, which man must understand and face with calm. While people are subject to regulation and limitation by Heaven and its mandate, they can cultivate their virtue and make great achievements through continuous efforts. That’s why people should rejoice in complying with Heaven and its mandate.

[A sage] can adapt appropriately to the changes of things without going too far. They rejoice in complying with the way of heaven and recognize the limitations set by the mandate of heaven, and so are free from anxiety. (The Book of Changes)
