Editing The World of Yetzirah (section)

== Its Nature ==
Olam HaYetzirah is the second world among the three worlds of BY"A, whose purpose is the descent and constriction of the light received from Olam HaAtzilut, where Ohr Ein Sof (Infinite Light) dwells and unites with it in complete unity, until the formation of Olam HaAsiyah, which is the lowest world with nothing beneath it, close to the dwelling of the chitzonim (external forces) and klipot (shells).

Specifically, Olam HaBeriah is the first world that was formed as a separate world in relation to Olam HaAtzilut, which is in complete unity. After the formation of Olam HaBeriah in the aspect of "something from nothing" from Olam HaAtzilut, the light descends further until the formation of Olam HaYetzirah, which is in the aspect of "something from something." The difference between Olam HaBeriah and Olam HaYetzirah is that Olam HaBeriah is formed directly from Olam HaAtzilut, and therefore its source is felt within it, to the extent that it is called the World of the Throne, which is a vessel for the revelation of the lights of Olam HaAtzilut. In contrast, Olam HaYetzirah is an additional stage in the constriction of light, since it is created from Olam HaBeriah, and therefore its source is not felt within it.

In Olam HaYetzirah, the separate reality from Elokut (Divinity) receives form (in addition to its substance that was created in Olam HaBeriah), and through this it becomes an actual reality, hence its name - Yetzirah (Formation).

However, in relation to Olam HaAsiyah, which is the lowest world among the worlds of ABY"A, Olam HaYetzirah is still in the aspect of divine revelation. Olam HaYetzirah is the revelation of what was concealed in Olam HaBeriah, unlike Olam HaAsiyah, which is the formation of something external and novel. For this reason, Olam HaBeriah is in the aspect of thought, while Olam HaYetzirah is in the aspect of speech, and thought comes to revelation and expression in speech, but it is far from action, which corresponds to Olam HaAsiyah, which is in the category of the formation of something entirely new.
