The ‘beginning’ that is called ‘Father’ is in the letter י Y of the name and its light is from the Holy Mazala. The letter Yod is spelled יוד and it means that the letters וד Vav and Dalet are included in it.
The name ‘Father’ indicates that it is father for other ‘faces’. These are ‘Mother’ ה, Zeir Anpin ו and Malchut ה.
The ה H of Mother is constructed from ו Vav and ד Dalet.
The Holy Ari teaches us that the first letter H of the name that represents Binah should be written in the Torah scroll as a Dalet and Vav with a line that move forward to indicate that Binah continues light from Chokmah.
Vav is Zeir Anpin and the Dalet is Malchut.
Every Hebrew letter starts with the letter Yod to tell us the ‘Father’ is the seed for all the letters and at the same time also the end of all because the Light of Chokmah, Father, is desired and revealed in Malchut.
The regular form of the Letter H is Dalet and inside of it the Yod of Chokmah, upside down to tell that it reflects teh light of Chokmah in Malchut.
The ‘river’ that comes out of Chokmah is Binah and it is called the world to come because it always comes without breaks. This is the ‘Eden’ of Tzadikim that will merit the world to come and its continuous flow of Light.
“וְנָחֲךָ יְהוָה, תָּמִיד, וְהִשְׂבִּיעַ בְּצַחְצָחוֹת נַפְשֶׁךָ, וְעַצְמֹתֶיךָ יַחֲלִיץ; וְהָיִיתָ, כְּגַן רָוֶה, וּכְמוֹצָא מַיִם, אֲשֶׁר לֹא-יְכַזְּבוּ מֵימָיו”
“And YHVH will guide you continually and satisfy your desire in scorched places and make your bones strong; and you shall be like a watered garden, like a spring of water, whose waters do not fail.”
The ‘water’ is flow of Light from Eden that is the י Y , nourish the ‘Garden’ that is Zeir Anpin, וד Vav Dalet as explained above.
“וְנָהָרּ יֹצֵא מֵעֵדֶן לְהַשְׁקוֹת אֶת הַגָּן וּמִשָּׁם יִפָּרֵד וְהָיָה לְאַרְבָּעָה רָאשִׁים”
“A river flowed out of Eden to water the garden, and there it divided and became four rivers.”
In the book of Rav Yeva Saba who is Saba D’Mishpatim we learned that the Garden is Zeir Anpin ו Vav that continues the Light of Binah to Malchut, ד Dalet. Everything is included and come from the Yod.
The letter Yod is a dot that represents the initial light that revealed in the process of Creation and therefore it includes everything in it. A Torah scribe starts every letter he writes in the Torah by lowering the pen to the parchment and make a simple dot/line to represent the initial Yod, then he raises the pen and lower it again to complete the letter.
Our consciousness is very important when we start an action. It’s the first manifestation of a whole plan and therefore very important. If we don’t have the Light connected to the action then there’s only physical energy that doesn’t have long life or blessings attached to it.
“אִם-יְהוָה, לֹא-יִבְנֶה בַיִת– שָׁוְא עָמְלוּ בוֹנָיו בּוֹ”
“Unless YHVH builds the house, those who build it labor in vain”
