Shared environment means the state of sharing and mutualism. Every object in the universe is interacting with each other, and depending on each other. The existence and development of every life is the accumulation and gathering of numerous karma. Hence, seeing is not necessarily true, which means not to be overly obsessed with the recognition of the appearance of things, but to focus the integrated causes and conditions that are closed related with what you see, therefore, to reach the realm of me in you, and you in me. Only in this way can we arouse the power of inner peace, and then get along with the world better!
