What is greater: nevua or ruach hakodesh?
Which one is a higher level, prophecy or holy spirit?
In Yerushalmi Succa Perek 1 Halacha 5 we find Yona ben Amiti, a novi, went to simchas beis hashuava and had ruach hakodesh.
But if he was a novi, ruch hakodesh is not as great seemingly.
See Rambam. Hilchos Yesode hatora Perek 7 Halacha 1.
