As it is written in The Book of Zohar: When a Cohen stood up below, he spread his hands, all the sacred Sefirot above were awakened and corrected to be blessed and receive Light from the depth of the well of Bina that constantly comes down to them. And the blessings don’t stop; they come down and turn into sources for all the worlds.
A Cohen (priest) is the upper part of the spiritual structure called a Partzuf. When he stands up and spreads his hands, his blessing comes down from above to Malchut. In this way, she is awakened below, and then all the characteristics of Malchut ascend from below to above with bestowal and love. They ascend to the upper worlds.
All of the Sefirot from Bina to Malchut are called a “well.” The more that Malchut is connected to Bina, this well is alive and flowing. Otherwise, it is just a pit without any water. If the well is full of water, but it is covered with a stone, it means you must carry out particular conditions to open it and draw water from it.
In the Torah, the meeting of the patriarchs with their future wives almost always happened next to a well. If the woman accepted water from the hands of the man, this meant that she was appropriate for him because water is the connection between Malchut and Bina. In this way, by means of the upper and lower waters, mutual interaction took place between them.
