When the woman comes before the priest, he explains the curse that she may bring on herself if she’s not clean. After she answers Amen twice to accept the outcome that could be harsh for her, the priest continues with the process.
If the woman is innocent from the charges brought on her, the positive outcome as we see below is great for her.
The priest writes the curse in a book with holy names in two forms. One is in the correct sequence of letters, YHVH, for the aspect of mercy and in reverse, HVHY, for the aspect of judgment. He then pours water on the book washing the names into a vessel for the woman to drink.
The Holy name YHVH represents the levels of Keter and Chokmah in the ‘Y’, Binah in the ‘H’ and Zeir Anpin in the ‘V’. They are all sefirot of Light over the ‘H’ of Malchut that represents the female and empty vessel with desire for the light. The reverse order of the letters, HVHY represents judgment because the Malchut is on top, without light of its own.
If the woman is innocent, the letters of judgment leaves the water and she becomes pregnant with a pure and beautiful child. If she’s not then the water turns into snake in her body (Naso #73).
“יָּבֹאוּ מָרָתָה וְלֹא יָכְלוּ לִשְׁתֹּת מַיִם מִמָּרָה כִּי מָרִים הֵם עַל כֵּן קָרָא שְׁמָהּ מָרָה”
“When they came to Marah, they could not drink the waters of Marah, for they were bitter; therefore, it was named Marah.”
Rabbi Elazar opened and said; I wonder how can people of the world are not busy with the Torah to reveal its secrets.
