I tend to take the pragmatic approach rather than the philosophical one as intellectualising about a condition will not change it in any way. "If something works, use it" is my paradigm.
Then who cares if it is the correct Kabbalah or not.
If one is neg-infected one has to act and do what one can, and if one stumbles in the dark, so be it.
Every step taken is better than not taking a step at all.
