In Hinduism, non duality is frequently associated with the Advaita Vedanta tradition of Adi Shankara. In this tradition – although there are others that share its precepts – it is thought that the multiplicity of the whole of existence can be reduced to one essential reality. According to the Madhyamaka school of Buddhist thought, there is a non-dual relationship between conventional and ultimate truth. In other Buddhist traditions, more emphasis is placed on the 'false' duality of the mind and the body, where only consciousness really exists. In Zen traditions, more is made of how different concepts can connect with one another in perfect ways, so-called interpenetration.
