According to the Three Truths, all things exist by virtue of their dependence upon all other things, and each thing contributes to the existence of all other things. Another way of saying this is that all things are manifestations of the underlying process of cause and effect, which unites them all. If all things are temporary manifestations of a single all-encompassing network of cause and effect, then nothing is truly separate from anything else. Body and mind, living beings and their environment, even the realms of delusion and awakening are not ultimately separate. They are all part of a single reality, which is revealed when one puts the Lotus Sutra into practice through Namu Myoho Renge Kyo.
