Kahunas are the magic workers on the Hawaiian Islands. According to Max Freedom Long in Recovering the Ancient Magic there are three groups of kahunas.
1. Various kinds of mediums, few of which ever accomplish any results of value.
2. A group using the lesser magic. Better than psychologists in the West, but not all that great.
3. Those who can use the powers on the plane of realization (from what I call the Info region of the soul). These kahunas perform feats that are miracles to Western eyes.
