@Princeharris1993 The Kamui page was put together by the Naruto Fandom, so it can be discredited. There is no referencing used as evidence for Kamui being "the only way in and out of the dimension", the only referencing around it explains why Obito is immune to harm during intangibility (chapter 666 page 5) and how he can use genjutsu on people trapped in Kamui to keep them subdued (chapter 520 page 9) (why would Obito need to subdue people with genjutsu in the first place if they possess no ability to escape from Kamui?). There is no explanation accompanied with evidence that states Kamui is the only means to escape the Kamui dimension.

^ If you say that Sasuke's ability to summon Garuda in Kaguya's dimension is a mistake, what prevents this from being the same case, but by the page writers for this website. Their claim that Kamui is the only access to and from the dimension is speculation. And if you cannot prove Sasuke summoning Garuda to be a mistake, then there should be no reason for the paths of Pain to be unable to reverse-summon.

You're right, it isn't stated that the Rinnegan enhances a person's summoning abilities, but it is explicitly shown, Pain/Nagato has not shown the need to utilise standard procedures of summoning jutsus with blood sacrifices, hand seals etc, and he has never shown strain in his incessant spamming of summoning jutsus, including the initial summoning of the Gedo Mazo. You used the Fandom page as a way to refute another way of entering Kamui, so I can do the exact same by your logic in regards to the Rinnegan improving summoning abilties; the Rinnegan > Animal Path Fandom page states the benefits that accrue by using the Rinnegan to summon entities, the ones I have listed above.

However, I do not need to rely on this, as I literally have the best example possible concerning Sasuke. Obito himself stated (chapter 683 page 14) that Kaguya's space-time jutsu is a lot like his own, and the fact that Sasuke was able to summon Garuda to a dimension most likely farther than Obito's pocket dimension, supports the idea that the paths of Pain can be reverse-summoned. And the only way to explain how Sasuke was able to do this, is something that sets him apart from every character that was in Kaguya's dimension: his Rinnegan, a trait he has in common with Pain.
