@Angela Davis I think Sasuke manifested his Rinnegan via the chakra he got from Hag. Hag gave half his chakra to Sasuke, and to me this half chakra is composed of half Hag's Yin Chakra and half Hag's Yang Chakra. Sasuke's Indra (Yin) Chakra then reacted with Hag's Yang Chakra to upgrade his Sharingan to Rinnegan, and Hag's Yin Chakra is left to use the Six Paths: Chibaku Tensei.
