Why is Da’at missing from the classic Sefirot? Why is there an empty asterisk where a Sefirah should be? My tentative answer is: we ourselves occupy that position, and understand from it, in a way that is not itself understood for precisely the same reason we cannot see our own sight or hear our own hearing.

To really understand the Sefirot, we must harmoniously understand the whole Sefirot fourfoldedly (PaRDeS) … from our fourfoldedly whole strength-soul-heart-am / nefesh-ruach-neshema-chayah self … across the interlapping fourfold Assiyah-Yetzirah-Beriah-Atzilut Olamot.

The Sefirot, of course, is a symbol — an intellectual icon through whom we can approach the infinite via the finite. Were it ten-thousand- or ten-billion-fold more complex, it would still be a gross simplification.

The Sefirot is divine design: the optimal simplification.
