Urashima - The First Otsutsuki wrote: About what you said about the two families, Senju and Uchiha combining their chakra tomcreate the Rinnegan, I’m afraid that’s not entirely true. The Rinnegan can only be created by mixing the chakra of two of Indra and Asura’s reincarnations. Indra Otsutsuki was the projentitor of the Uchiha Clan, and Asura Otsutsuki was the progenitor of the Senju Clan. Madara and Hashirama are the reincarnations of Indra and Asura respectively. So, when Madara combined his chakra with Hashirama’s, (his cousin and at the same time, his brother, which is weird), he obtained the Rinnegan. Also, the Rinnegan and the Tensaigan are parallel Dojutsu in a way. The Rinnegan, or Samsara eye, and the Tenseigan, or Reincarnation eye are clearly linked. Samsara is a concept from Hinduism and Buddhism, and it has to do with the realms of Reincarnation. Whereas the Tenseigan represents the reincarnation itself. Also, they do share the ability to manipulate gravitational forces.

Ah yes I overlooked the fact that it’s only Indra’s and Asura’s reincarnations, however they’re only born in families of the such desendants, so the main point about Hagoromo’s chakra I was making still stands
