Kabalistic definition
Kabalistic sources, strictly speaking, means the Zohar (a book whose origins are of some debate, but was written some time between 200 C.E. and 1200 C.E.) and its progeny in Jewish mysticism. While most Kabala scholars do not engage in much practical legal analysis, there are many Jewish Legal experts who incorporate mysticism into their response. One such expert is Rabbi Shneur Zalman of Liadi, who famously rewrote his own codification of Jewish law according to kabalistic sources though large portions of that manuscript were lost in a fire.
