I don't see how Kaguya being the Juubi would discredit what he just said..You're wrong.
The Juubi is merely Kaguya. Indra's Sharingan is a result of the chakra fruit from the tree. What Asura's bodily powers entail is simply extremely high chakra and stamina. Stop making things up to suit your arguments. The scans show that Hagoromo gave his power to Asura only the first time, and then decided to give it to Indra the second time.
If the Six Path's Senjutsu was his Kekkei Genkai, the Senju would have inherited it but they only inherited his bodily powers. You know it to be true. Stop revising it.
OP: I disagree
When Hagoromo said that, he was using it as a comparison to the power he literally gave Naruto and Sasuke. Just giving Ashura power doesn't have to mean that he have everything he had to Ashura. It could simply mean that he gave Ashura some of his power (could be RSM) while not giving Indra anything at all.
The other scans you posted don't exactly have to contradict that. Since he was referring to actual power when he said that, the conclusion I draw in this would be that at some point he reached Indra's power on his own as Hagoromo also stated. In which case, Indra was a prodigy so he would've been able to improve on his own. Especially if Ashura, who was inferior, caught up to him. Once he was on the top again, Ashura received power from Hagoromo and once again reached Indra.
This is the only conclusion I could draw so far but it can't be a fact if it was never shown. However, I strongly believe that he was referring to actual power since he was comparing it to the power he gave Naruto and Sasuke.
