According to the original intention of the Diamond Sutra, it tells you the truth of the world, and the method of liberation derived from the basic concepts of the underlying operating logic of the world of "emptiness" and "impermanence", that is, let you not be attached, do not be attached to the unchanging, the only unchanging thing in the world is change. You must know how to face change, understand change, and understand the inevitability of the process of "movement, residence, destruction and extinction". Because nothing is permanent, it is all just the interaction of fields.
