551) “Behold, I am sending an angel before you.” The Assembly of Israel, the Shechina, said, “May he kiss me with the kisses of his mouth.” It should have written, “Love me,” and not “Kiss me.” However, kissing is clinging of spirit to spirit. This is why kissing is with the mouth, since the mouth is the outlet and the origin of the spirit. Hence, kisses are with the mouth, with love, attaching of spirit to spirit when they do not part from each other.
552) For this reason, one whose soul comes out in a kiss clings to the spirit of the Creator in a spirit that does not part from Him. This is called “kissing,” and this is why the Assembly of Israel said, “May he kiss me with the kisses of his mouth,” to attach spirit to spirit so they will not part from one another.
553) “For your love is better than wine” means the wine of Torah. Mochin of ZA is called “Torah,” and Mochin of illumination of Hochma is called “wine.” “And wine which makes man's heart glad” is written about the wine of Torah. It is written about that, “For your love is better than wine, meaning it is better for the gladness of the heart than wine, which makes me glad more than anything.
Kissing is with the lips. There are two discernments in the lips: 1) The upper lip is upper AVI, which give pure Avir there, which is light of Hassadim, called Ruach [spirit], in a never ending coupling, and in which the Yod never leaves their Avir. 2) The lower lip is YESHSUT, in which the Yod comes out of their Avir and returns to being light of Hochma, giving there illumination of Hochma.
Although the illumination of Hassadim of upper AVI is actual GAR, still ZA needs illumination of Hochma, and the light of Hassadim of AVI in him are only VAK without a Rosh due to the absence of illumination of Hochma. However, once ZA receives the Mochin of YESHSUT, illumination of Hochma, the Hassadim of AVI become actual GAR in him, just as they are in upper AVI themselves, since now it, too, is completed in illumination of Hochma and there is no flaw in him, just as in upper AVI. Their illumination of Hassadim is more important than the illumination of Hochma in YESHSUT because they are superior to them and to the ones who give to them.
“May he kiss me with the kisses of his mouth,” to attach spirit to spirit. Illumination of Hassadim is Ruach in the upper lip, upper AVI. The lower lip is illumination of Hochma of YESHSUT, which complements the Ruach of the upper lip to make it GAR, as in AVI themselves.
“For your love is better than wine” means the wine of Torah, since because the lower lip shines there, too, which is illumination of Hochma from YESHSUT, which is called “wine,” your love, which is the Ruach from the upper lip, has become good, since by that the Hassadim have been made in GAR. This is why the Shechina says in a coupling of Neshikin, “For your love is better than wine.”
554) “Jacob kissed Rachel, and raised his voice, and wept.” When he was in clinging of the spirit in her, the heart could not bear and wept. It is written, “And kissed him, and they wept,” since the spirit did not cling to him at all. It is written about that, “Deceitful are the kisses of an enemy.”
One who kisses with love attaches spirit to spirit with adhesion of love. One who does not kiss with love is not in adhesion, but rather “Deceitful,” which is coarseness, since his spirit is not adhered to a kiss and he does not cling to it at all. This is why it is written, “May he kiss me with the kisses of his mouth,” which is adhesion of spirit to spirit.
555) As long as the Creator goes in Israel, it is as though a spirit clings to a spirit. It is written about that, “And you that cleave unto the Lord” in all those manners of adhesion, and do not part from one another. When it is written, “Behold, I am sending an angel before you,” Moses knew that this was retirement from Israel. He said, “If Your presence does not go with us, do not lead us up from here.”
556) Above it, it is written, “You shall bring the first fruits of your soil into the house of the Lord your God. You are not to boil a kid [young goat] in its mother's milk.” This is so in order to not mix a lower matter with an upper one, so that the outer side will not suckle from the side within. The one without, the kid, is from the side of impurity, and the one within, its mother, is from the side of Kedusha [holiness]. Its mother is the Assembly of Israel, Malchut, which is called “mother.” Since the expansion of Malchut is only through the shells, as it is written, “And her legs go down to death.” “In its mother's milk” means that those who should not, will not suckle from that side.
