There is also this from chapter 7: The Nine Tails was still living inside Naruto. There were also remnants of the other 8 bijuu inside him as well. In that way, you could say he was a human pillar for the power of the Ten Tails. In the last war, Obito had become a human pillar for the Ten Tails and gained chakra rivalling that of the Sage of the Six Paths. Naruto, who’d taken the bijuu into him as well, had some of the Sage’s power even now. But it doesn't outright state that the Sage's power was a result of the remnants of the tailed beasts. Whereas Jin no Sho does say that Naruto's Six Paths Sage Mode was thanks to the power he received from Hagoromo, the same as Sasuke's Rinnegan.
