It can also be translated idiomatically as "the wheel rotates and life revolves." My dictionary explains the idiom as "all things being in flux through the endless circle of birth, death, and rebirth."

So, yeah. If you're making up a term for a fanmade dojutsu, I suggest something a bit more meaningful, probably linked to Buddhism.

To be perfectly honest, I tried, but I was exhausted from work at the time and kind of gave up after a while. And since Kaguya's dojutsu would encompass the powers of all the other Great Dojutsu, I went with Gōkeigan. :p

To be fair, though, only the Rinnegan and Tenseigan seem to use Buddhist aspects- the Sharingan ("Copy-Wheel eye") and Byakugan ("White eye") don't seem especially connected to Buddhism. And I'd contend that Gōkeigan is still at least a tad more creative than "Rinne Sharingan".

As for the powers of the Tenseigan, in addition to the two named techniques Toneri uses (Kinrin Tensei Baku and Ginrin Tensei Baku), it also grants him ten Truthseeker Orbs, and the ability to fly, absorb chakra (similar to the Preta Path), and manipulate attractive/repulsive forces (similar to the Deva Path). Of course, he's the villain and had to get defeated in what basically amounts to a 10 minute fight scene, so it's likely that we didn't see the true extent of its abilities.

Granted, but even factoring that in, everything we did see had either already been used in some fashion before, or else just seemed extremely unimpressive. You would think Kishimoto would have tried a bit harder to give the Tenseigan its own unique flair.
