At time of Creation, Malchut, restricted herself from receiving the Light. Also the lowers, that were created form Malchut, were not able to receive the upper lights.
The Creator elevated Malchut to Binah to receive from it’s light. When Malchut came to the same level she received the same shape, which is the letter ה.
At that moment Chokmah expanded to יוד, Binah to הא and Malchut the same as Binah הא. The א here is the original thought of creation with the original love that is used as power to elevate the emptiness of Malchut to Binah and connects the upper י with the lower י of the unification of Light and vessel. That is the י of יהוה and the י of אדני.
That created the 32 channels (numerical value of יוד־הא־הא) to Malchut. When Malchut distant itself again, the light stayed above and Z”A, ו, created by Binah to became the conduit for the Light of Binah to Malchut.
The vessel and the Light got connected. The tool that we received to connect it the Torah, which is our connection to Zeir Anpin, ו, the bridge of 6 to Shabbat, Binah.
