It states, Moshiach will appear, be accepted by some of the Jews, disappear, and then return to be accepted by everyone, but the question can be asked, why does he need to disappear? because the ultimate goal of Moshaich is not himself – as the Rebbe teaches, he is only God’s agent – Moshiach like Mosses (said) “I am here to connect you to God.”

Now when a great light shines, a small light feels insignificant, and removes its light in face of the greater light.

So particularly, after Moshiach disappears can a personal union with God begin.
