Holy Zohar text. Daily Zohar -344.

Tikkun 21 – 85

The Torah has two parts, the written Torah and the oral Torah.
The Torah scroll is the written part and the oral Torah is the study of it that reveals its 70 inner dimensions.

Numbers 11:16 “וַיֹּאמֶר יְהוָה אֶל-מֹשֶׁה, אֶסְפָה-לִּי שִׁבְעִים אִישׁ מִזִּקְנֵי יִשְׂרָאֵל”
“And YHVH said unto Moses: ‘Gather to Me seventy men of the elders of Israel”

God instructed Moses to gather 70 elders to bestow upon them the wisdom to lead the Israelites.

Numbers 11:17 “וְיָרַדְתִּי, וְדִבַּרְתִּי עִמְּךָ שָׁם, וְאָצַלְתִּי מִן-הָרוּחַ אֲשֶׁר עָלֶיךָ, וְשַׂמְתִּי עֲלֵיהֶם”
“And I will come down and speak with you there; and I will take of the spirit which is upon you, and will put it upon them”

Moses and Aaron together made 72, which are the number of channels that reveal the supernal light in the world.

The Torah is the heart לב of this existence. It is the first and last letter of the Torah and numerical value of 32, as in the 32 times the name of God appears in the story of Creation and builds the 32 paths of wisdom to Malchut.
My heart is לבי and with the 10 for the letter Y it gives us 42 for the concealed heart of the Torah that ‘beats’ life into everything. It is the first 42 letters of the Torah and the concealed 42 letter name, known as Ana B’Koach.

ללבי is ‘To My Heart’ with numerical value 72. It is the ‘pulse’ of the concealed heart revealed in Malchut, our life. When we connect to the study of Torah on its higher level, which is the Zohar, we are one with the heart of creation on all levels.

God connected his ‘heart’, which is the Torah, to Moses, Aaron and the 70 elders. The same light also bestowed on Rabbi Shimon who shares it with us in the Zohar through the study and revelation of the 70 dimensions of the Torah.
Through our Zohar studies we connect our heart to the supernal heart.
