The Zohar, Chapter “VaYigash (Then Judah Approached),” Item 2: However, everything was created in the Torah, and everything was perfected in the Torah. And as the Torah begins with Bet, the world was created in Bet. This is so because before the Creator created the world, the Nukva, all the letters came before Him and entered one at a time in reverse order, in the order of Tav-Shin-Reish-Kof and not in the order of Aleph-Bet-Gimel-Dalet.
Item 3: The letter Tav came before Him and said, “You wish to create the world with me.” The Creator replied, “I do not, since many righteous are destined to die in you. …This is why the world will not be created in you.”
Item 4: The three letters, Shin-Kof-Reish, approached each on his own. The Creator told them, “You are unfit for the world to be created in you for you are the letters used for reading Sheker [deceit/falsehood], and a lie is unworthy of rising before Me.”
This can be compared to how we ask the Creator to help us unite the desire (Kli). The letters are the formation of Malchut. Essentially, it is her that we are trying to construct from our points in the heart.
Hence, if we come to the Creator with our desire (although we don’t presently realize it), crying like infants not knowing exactly what to ask, it works as though we are appealing to the Creator in all kinds of forms and letters. Yet we get nothing in return until we discover the correct desire or the correct letter.
Item 5: The letters Peh and Tzadik approached, and so did all of them until they reached the letter Chaf. When the Chaf descended from the Keter [Keter written with Chaf in Hebrew], the upper ones and the lower ones were shaken, until everything came to exist in the letter Bet, which is the sign for Beracha [blessing], and in it, the world was perfected and created.
We have to attain a desire, a state where only the blessing from Above can give birth to our spiritual vessel. Only if we join the force of blessing and become one with the Creator (and not by any other efforts of ours) can we acquire the spiritual Kli.
