“ וְאָכַלְתָּ, וְשָׂבָעְתָּ–וּבֵרַכְתָּ אֶת-יְהוָה אֱלֹהֶיךָ, עַל-הָאָרֶץ הַטֹּבָה אֲשֶׁר נָתַן-לָךְ”
“And you shall eat and be full, and you shall bless YHVH your God for the good land he has given you.”
Eating food can be a high spiritual connection. The blessing of “המוציא”, “Hamotzie” over the bread connects the first H and the last H of the YHVH name.
The blessing over the food connects the food to the three columns, Abraham (Chessed, Right), Isaac (Gevurah, Left) and Jacob (Tiferet, Central). They are mentioned in the blessing because they provide the access to the level of Binah. In the words of the blessings we use the words that God used to bless them; “Bakol, Mikol, Kol…”. These words connect to the Torah where the blessings of God to Abraham, Isaac and Jacob are mentioned. With their support we draw the Light from Binah through Yessod to Malchut.
There are four main blessings that we recite after eating the food. The first one created by Moses to give thanks for the Mana that came down from heaven. The Second was made by Joshua when the Israelites entered the Promised Land and ate from it. The third one was added after the destruction of the Holy Temple and it asks for the building of Jerusalem. The sages added the fourth blessing to acknowledge that everything comes from God.
The Holy Ari gave great importance to the blessing of the food because it has immediate effect, by transforming the physical food we just ate into Light.
Remember that the body processes the food to get the energy from it. If we treat it only on the basic level, we may sustain the physical body and produce waste while some of it stays in the body. The blessings ‘wrap’ the food we ate in a spiritual envelope and add light to our vessel.
