Maran (pronounced Muchun) Hagaon Harav Chaim Kanievsky Shlita, has a whole (small) chapter in Orchos Yosher called “Ruach Hakodesh”. He writes, as others have said, that there are different levels. I can’t go thru it all now, i’ll try to put it up soon.
He says the navuah that’s batul till moshiach comes is referring to real bona fide navuah. However, today we’re still left with some sort of ruach hokodesh.
Even though i hope to put up a better “quote” (hehe), i’ll mention something he says at the end which to me seems like a big reason for him writing the whole chapter in the first place. Also it sounds like people here need to hear this. There is a ruach hakodesh that can rest on a Talmid Chochom when someone asks him a shaalah. If i recall correctly, it’s possible that this whole ruach hakodesh comes from the one asking the question’s strong emunah in chachamim. Meaning even if one person asks Rabbi Ploni something and gets an answer with ruach hakodesh, that may not be the case when someone else asks Rabbi Ploni.
