Rinnegan is a seperate eye, created by the fusion of Asura's & Indra's Chakra. Izanagi is the practical application of the creation of all things ability Hagoromo utilized to manifest the Tailed Beasts. Basically, it's making fantasy a reality, and can be achieved only through Hashirama's and Uchiha's powers, ie; Mokuton and Sharingan.
