The holiday of Shavuot comes on the 50th day after Passover. For 49 days we perform the Omer count, which is like counting tied bundles, because the main work of man is to bind himself with the Creator. If we bind all of us together with our desires and intentions, we create one common vessel, we create a place for the revelation of the Creator’s light.
There are seven Sefirot in the soul, seven qualities that are developing in the head of the spiritual Partzuf (Rosh): Hessed, Gevura, Tifferet, Netzach, Hod, Yesod, and Malchut. In each Sefira, there are another seven Sefirot, that is: 7 x 7 = 49, and combining all together, we get 50.
Therefore, on the 50th day after exiting Egypt, from the moment we began to correct our spiritual vessel, the connection between us, we come to this special day when the connection between everybody emerges. This day is called the holiday of Shavuot.
In Egypt, we were still under the control of the desire to receive and could not connect with each other. Pharaoh kept us in slavery and did not allow us to connect with each other. When we escape from the slavery of Pharaoh, we can begin to connect, and that is why we run away from him. After all, it was very good in Egypt in the corporeal sense. It was bad only in the spiritual sense because of the inability to connect.
Those who wanted to connect, considered it a spiritual gain and were not afraid to sacrifice material things for this purpose, they came out of Egypt. After that, when we start to connect with each other, we come to the state of Omer, a bundle. So, we join part by part, counting these bundles until we reach the last, 49th day in the Omer count when we are already able to receive from the Creator the light that will fill us.
And for 49 days, we were receiving only the light of correction, so it was called the Omer. Each time, we found egoistic qualities between us that did not allow us to connect, but we tried to correct them and connect them, until on the 50th day, everything finally connected and we reached the common quality of mutual bestowal between us and from us to the Creator. Now the Creator can also give us the light and this is why it is called the day of the giving the Torah.
The symbols of this holiday are milk, the sign of bestowal, and a connected group bound together in one bundle (Omer) and in adhesion with the Creator.
