Leshem - Rav Shlomo Elyashiv

Rav Shlomo Elyashiv (January 5, 1841 - March 13, 1926), also known as the Leshem or Baal HaLeshem, was a tzakkik and kabbalist, whose true greatness remains hidden until this very day. The Leshem did not utter any word without reason and he enclosed himself in his room wearing tallis and tefilin, learning both Toras HaNigla and Toras HaNistar day and night.

The Chofetz Chaim made the following two statements about the Leshem: "In this world we can stand in his presence but who knows if in the Olam HaEmes we will even be able to get near him." "While we build in this world and have in mind to build the heavens, he with his clear vision of the pathways of heaven builds the heavens themselves."
