The Leshem, a great Lithuanian/Misnagdic kabbalist (i.e., in the tradition of the Gaon, rather than the Besht), in his book Hakdamot u-Sh'arim, gate 1, elaborates a distinction between giluyim (=manifestations) of divinity and toldos he'arah (=derivative illuminations).
The giluyim are divinity itself. We can have no grasp of their essence. They are metzumtzam (=limited, from the same root as tzimtzum) to not extend beyond the bottom boundary of the world of Atzilut. From there downwards only toldos he'arah extend, flowing into the worlds of Bri'ah, Yetzirah, and Asiyah, and making up the innermost soul of these lower worlds.
In this way, perhaps an approach is suggested that respects certain aspects of Halakhah--the careful delineation between what is holy and what is not, what we may ascribe divinity to and may not--and which, also, does not pass over our everyday subjective experience of reality as composed of multiplicity and often pain---but does ultimately root reality, in its deepest sources, in divinity.
