Does the term "Six Paths Senjutsu" only refer to a single senjutsu (sage technique) that gives the user access to Truth-Seeking Orbs and flight, or does it refer to multiple jutsu like the term "senjutsu" on its own does (as in, Madara's Sage Art: Storm Release Light Fang, Truth-Seeking Orbs, etc.)?
Example:
"The Six Paths Senjutsu gives one access to Truth-Seeking Orbs and flight," vs. "Madara's Sage Art: Storm Release Light Fang is a Six Paths Senjutsu, and his Sage Art: Yin Release Lightning Dispatch is another Six Paths Senjutsu."
