And there are two HVYHs: to the right and to the left, like this: Y-Q-Q-V and Y-V-Q-Q.
Yod י is to the right, and of it: (Prov. 3:19) Y”Y in wisdom∞ḥokhmah established the Earth... Father with Daughter, higher Hei ה with Son, which is Vav ו – the phylacteries upon his head. It is this that is written: (Is. 62:8)... and by the arm of His strength... – these are the phylacteries (tephilin) of the head,cxviiBT Berakhot 6a for wherever the letter Hei ה is upon Vav ו, it is Mother.
And this is the mystery, of the ‘rising and descending offering’. For Hei ה ascends towards Yod י, and Hei ה descends towards Vav ו. And if not for this HVYH: Y-Q-Q-V – which is alluded to in this verse: (Jer. 9:23)... rather in ‘this’ (zot) should boast the self-praiser, that he understands and knows Me... acronym Y-H-H-V – people would not know about ‘the ascending and descending offering’.
