Most of the blessings we say begin with six words “בָּרוּךְ אַתָּה יְהוָה אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם”. The six words bring the aspect of the act of Creation. It is the aspect of the upper of lower triangles of the Shield of David.
The Zohar explains that the word בָּרוּךְ ‘Baruch’ is connects to the root of the Light that flows from Chokma and Binah. The first letter ב is like the root of the entire Torah in the word “בראשית” “In the Beginning…”.
אַתָּה – ‘Atah’ – This word begins with the first letter of the Hebrew Alef-Bet, the second letter is the last letter and the third letter is the letter of Malchut from the יהוה YHVH name. The Holy Ari explains that this word creates the path from the Root, which is represented by the letter א. The path continues through all the Hebrew letters to ת .ת is also the last letter of the word Malchut, מלכות, the Sefirah that defines our material world.
The first four words establish connection to the upper Light and are considered as external/potential Light.
The next two words meet our level and define the vessel that is ready to receive and reveal the Light.
מֶלֶךְ הָעוֹלָם – Melech Ha’Olam – Means ‘King of the world’. The world is Malchut and the King is the force that ‘governs’ the wold of Malchut.
With the first four words, we meditate on drawing the Light and with these two we want to reveal this Light by ‘submitting’ it to the ‘King’. We meditate to nullify our self and be ready to accept the four types of death. This meditation creates affinity with the Light and allows us to benefit from the revealed Light.
The words that follow the first six are the aspect of the seventh element, Malchut, which is the purpose of using the first six.
God created the world in six days for having the Shabbat that is all about rest and out of the correction process. The world goes through Tikkun process of six millennium and the seventh one is all about the end of the Tikkun, complete peace and rest.
The seventh part of the blessing defines the type of Light we will receive so every blessing is unique and benefits different parts of our soul.
