Numinous value. Over-excitement in the service of God.
Also we do find that the world of Kabalah deals with a different planes of existence than the Oral Law.
This we can see right away in the Zohar itself. The Zohar takes mitzvot and applies them to areas that are clearly not legal parts of that mitzvah. That means that sometimes a person gets connected with what can be described as higher spiritual worlds. The idea would be that while a person is still in his physical body his spirit gets embedded in some kind of higher plane of existence.
But people looking for numinous value can find this kind of value in the Sitra Achara {the Dark Side} [a phrase made famous by Star wars movies but comes directly from the Kabalah].
Regardless of the problems with this area of value still there are people that interested in numinosity and they will get their thirst satisfied by someone illegitimate of they if they are lucky find someone or something legitimate.
But seems that numinous value can slip very easily from holiness into its opposite. It would be nice if there was some kind of test for this.
