The Rebbe: Moshiach will Teach Through Vision

...[T]he subject matters of the future Torah study taught by Moshiach, will be the esoteric teachings of Torah. But there will be another distinction.

The intellectual pursuit of the esoteric knowledge, will not follow the current temporal pattern, of a teacher imparting knowledge and comprehension; instead it will take the form of visualization:

We will comprehend, with the visualizing light of the supernal wisdom, to the degree, that we will all perceive with the vision, the innermost wisdom; and also, the heretofore utterly sequestered, secrets.
