Torah, “Leviticus” 23:16 – 23:17: You shall count until the day after the seventh week, [namely,] the fiftieth day, [on which] you shall bring a new meal offering to the Lord. From your dwelling places, you shall bring bread, set aside, two [loaves] [made from] two tenths [of an ephah] …
That is how the story about Shavuot (the festival of the giving of the Torah) begins.
Fifty days is the level of Bina. Bina is the characteristic of bestowal, the higher level. Malchut is the characteristic of reception, the lower level. There are seven Sefirot of Zeir Anpin between Malchut and Bina, which are the intermediary levels that separate between them.
Seven levels multiplied by the seven sub-levels in each one of them are 49 altogether, and the fiftieth level is Bina, the characteristic of pure bestowal.
Bread (a new meal-offering) specifically symbolizes the characteristic of Hassadim (mercy). So, bread is the foundation of all nourishment.
From a spiritual point of view, a powerful internal potential exists on this holiday, even though, externally, it is completely unrecognized.
It symbolizes the reception of the guidebook for the spiritual correction of a person, the receiving of the Torah.
However, in the spiritual chain of festivals, Passover, the Exodus, is considered to be more essential. We become detached from the ego and independent, free people. As it is said, we became a people, and from that moment everything depended upon us, whereas Shavuot gives a person the way to life. He gets a “graduation diploma,” he gets the Torah, and from here on, he continues with this guidebook. Yet, from here on, there exist stages that one must go through.
