Working from above and staying above, any transformation you effect does not last. Yet while it is there, it is all-consuming. While it is there, everything experiences a whole new state of being.
Working from within, the transformation is self-sustaining, but only skin deep. The beast within remains a beast, just slightly more enlightened. The world remains a world, only a brighter world.
Ultimately, both approaches are needed. We can teach and provide knowledge, yet preserve a sense of the transcendent and unknowable. We can work with the world on it’s own terms, but we must show it that it is only a world. Within a higher context, it is nothing at all.
Until, eventually, that beast and that world will become the devices through which an unknowable G‑d can be known.
