Awakening the Rinnegan


To awaken the Rinnegan, can you just get any Uchiha's and Senju's chakra, mix
them together and get the Rinnegan? Or do you need Ashura's and Indra's in
particular (i.e. their reincarnation's)?

Do you still need to go through some very sad or aggreviating situation to
awaken it, or do you automatically get it the moment you mix the two chakras
together?




To get the rinnegan you need to have the mixture of the Ashura and Indra
chakras. As Uchihas are descendants of some of them and the Senju of the
others, the mixture of these also allows obtaining it. The clearest example is
Madara who uses the chakra of the first Hokage to obtain it.

You do not need any more requirements, but it is not a trivial process Madara
itself took more than 10 years to wake up the rinnengan.
