We saw that the gematria of יְהִי אוֹר fits a pattern. Let us take it one step further. The GR"A was the light of Moshiach ben Yosef that started to shine in 5500. Chaim Vital was the light of Moshiach ben David which started to shine in 5366.
What is left is the light of Moshe Rabbeinu. This is what יְהִי אוֹר teaches us. The Arizal was the light of Moshe Rabbeinu, and light started shining into the world in 5332.
This light has been filtered, hindered, transformed into what is acceptable to the Jewish community, in particular to rabbinical orthodoxy, as Ramchal - the light of Moshe Rabbeinu of his time - taught in writing, and afterwards experienced in his life, through the ban on his works.
