Board Thread:Theories and Speculation/@comment-3568954-20150630000123

as he can use the Asura path to sprout mechanical replacements

unless he needs the sages body to use all of the paths

which gets me to my second theory

its my theory that the Rinnegan isn't required to use all the paths

its my theory that anyone who has Hagoromo's six paths chakra can use the paths if they learn how to which would make sense since the chakra itself is called the six paths chakra

its my theory that the Rinnegan simply allows you to use the Paths visually instead of using hand seals and other methods
