Let There Be Light - 2
153) “And God said, ‘Let there be light.’” It means that the expansion of that light would continue downward. These are the angels that were created on the first day. They can persist on the right side because the first day is Hesed, regarded as the right side, hence the angels that extend through it are considered right.
The word Yehi [let there] indicates that the Yod at the end of the word Yehi entered the Yod-Hey of the word, hence the light of Yod-Hey became Avir. For this reason, all the degrees were diminished until TNHYM of ZON fell to BYA. The angels, who are a separate light from Atzilut, were created from the expansion of the light of ZON to the separated BYA.
It follows that the angels of Hesed were created from the diminution on the first day, Hesed of ZA, the angels of Gevura were created from the diminution of the second day, Gevura of ZA, the angels of mercy from the diminution of the third day, Tifferet of ZA, and similarly the rest. Through the diminution made in the word Yehi, part of the light of Hesed spread below in the separated BYA. That is, they were created by the diminution of the light of the Sefira Hesed, which is the first day. Because of it, they can exist on the right side, who are the angels of the right, from the part of Hesed.
“And God saw the light, that it was good.” “The” comes to add and include the mirror that does not illuminate, the Nukva, with the illuminating mirror ZA, of whom it is written, “that it was good.” That is, the word “the” comes to add that the Nukva was included in the words “that it was good” together with ZA.
Also, the word “the” comes to add and include all the angels who extend from the light of Hesed, as they, too, are included in the words “that it was good.” All of them illuminate as the first light in complete existence because they are included in the words “that it was good,” written about the first light.
