6. Rabbi Yehuda said, The scripture proves this, THE PRECLUSION OF UNDERSTANDING ABOVE ZEIR ANPIN. For it is written, "For ask now the days that are past...FROM ONE SIDE OF HEAVEN (WHICH IS ZEIR ANPIN) TO THE OTHER" (Devarim 4:32). SO IT IS EXPRESSED IN THE SCRIPTURE THAT QUESTIONING AND UNDERSTANDING PERTAIN ONLY TO THE LEVEL OF HEAVEN, WHICH IS ZEIR ANPIN, FROM ONE SIDE TO THE OTHER. Up to here, one is permitted to observe, but from here and further, MEANING ABOVE ZEIR ANPIN, no one can comprehend it.
