The Zohar, Chapter “VaYetze (And Jacob Went Out) – Part 2,” Item 373: With all the offerings, it does not say, “Observe,” as it is written, “Shall you observe to offer,” since observing [(Tishmeru) is ”keep,” (Shamor)] is the Nukva, who should bring closer above, to ZA, as it is written, “Shall you observe to offer unto Me,” offer the Nukva in its time, in the right and left [lines] of ZA, who are Abraham and Isaac.
The whole essence of sacrificial offerings is to come closer, to build the middle line by classifying desires. Whenever possible, desires should be used for merging and connection. The ones that are impossible to use that way should be removed as obstructions and filed. One should connect the right and the left lines so that the “fire blazes” and the Returning Light rises to the Creator. All discernments are performed only through the “sacrificial offerings” of one’s egoism.
