Everything that exists in the temporal world of space and time are interconnected, interdependent, according to Buddhist teachings, interconnectedly dependent. Mind and body, subject and object, space and time, they do not exist independent of each other. Everything is interdependent. These days, so many eco-philosophers are saying that the biosphere itself operates on that principle of interdependency. Everything is interconnected and that is the unitive way of thinking, instead of thinking that there s mind as a separate thing, existing by itself, independently of each other, body and mind are interrelated, interdependent.
Nothing exists by itself, in itself.
Buddhist philosophy can be very complicated, but to put it simply, that s what emptiness means. You may have heard about Buddhist teachings with emptiness. Emptiness does not mean nothing exists. Emptiness means nothing has inherent existence. Everything is empty of inherent existence.
