6 belongs to the standard 1–9 range that every mainstream numerology school treats as a valid life path result. There's nothing exotic about it on its own.
As with 2/11 and 4/22, there's a pairing to watch for: 33 reduces digit by digit to 3 + 3 = 6, but most Western schools stop at 33 and preserve it as a master number rather than continuing on to 6. So a total that passes through 33 doesn't automatically become "Life Path 6" — it depends entirely on which convention is being followed.
