"A wise man, recognising that the world is but an illusion, does not act as if it is real, so he escapes the suffering." Buddha.
One of the fundamental teachings of Buddhism is the notion of Impermanence where all the forms that make up the universe are temporary - arising and immediately passing away and therefore without absolute identity.
Another is Emptiness. Buddhism teaches that reality emerges from emptiness. Emptiness represents a potential from which every possibility may arise
Another teaching of Buddhism is Oneness - the idea that everything in the universe is intimately interconnected; that all forms or occurrences are connected and dependent upon one another.
These 3 ideas parallel some of the findings of Quantum Mechanics.
