Five principles of Taoism. "Heaven" is the spirit of all things, because it is born in "Tao" with people and will always be in "Tao", so it is naturally "one". "Heaven" means incarnation. Heaven and man are the embodiment of Tao, all in a "Tao body", and naturally they are "one". "Heaven" refers to nature. The essence of Tao is nothingness. Heaven is born in the Tao, and nature is nothing. Therefore, the essence is not antagonistic, they are all in "nothing". "Heaven" refers to the environment, "man" refers to me, and "harmony" refers to "oneself and other environments", which are the same individual.
Confucian dichotomy. "Heaven" refers to the nature of all things, and "man" refers to human nature. Their nature is the same "nature", so it is called "unity". "Heaven" refers to an invisible saint, who is a silent teacher, selfless and tolerant, and always kind to everything in the world; "Man" refers to later disciples, and "unity" refers to respecting the holy line, practicing the holy way and becoming holy.
Three Buddhist meanings: Heaven refers to He, Man refers to Me, and the distinction between Me and He is called "integration". "Heaven" refers to illusion, "man" refers to the heart, and the heart cannot be confused by "illusion", which is called "unity". "Heaven" refers to mystery and "man" refers to consciousness. Breaking the mystery, we realize that "heaven and man" is not real, but the essence is emptiness and the pseudonym is existence. Suddenly realizing this truth is called "unity".
Therefore, the word "heaven" in this sentence means "saint" from the perspective of personification; The understanding of simulation is "heart"; The understanding of simulation is "public"; The understanding of simulation is "glory"; The understanding of simulation is "love"; It is a polysemous word, which changes with the context.
