The supernal palace that everything below depends on it is called ‘The palace of love’ as it is said;
“מַיִם רַבִּים לֹא יוּכְלוּ לְכַבּוֹת אֶת הָאַהֲבָה וּנְהָרוֹת לֹא יִשְׁטְפוּהָ”
“Mighty waters cannot quench love; rivers cannot sweep it away.”
The Holy name YHVH has the י Yod that is Chokmah with a tag that represents Keter and it’s always on top of it to tell us the Keter and Chokmah are unseparated. The H ה is Binah that connects with love to Chokmah and they can’t be separated.
Genesis 2:10 “a river goes out of Eden to water the garden”. The ‘river’ is Binah and ‘Eden’ is Chokmah.
The Light of Chokmah comes through Binah to the lower levels and they must stay unseparated to keep the flow of light.
When the V ו, Zeir Anpin and ה H, Malchut, connect together with love like a bride and a groom, then all levels are connected with love. The יY with the ה H the הH with the ו V and the וV with the lower הH.
Those who love YHVH connects to this love and draw from a higher level of love. That is why we are told in Deuteronomy 6:5 “You shall love YHVH your God with all your heart and with all your soul and with all your might.”
