Once when the Apter traveled to Lublin to see the Choze he took along his son R. Yitzchak Meir. When they were sitting in the Sukkah, R. Yitzchak Meir saw that the name of Y-H-V-H was engraved on the Schach. The Apter remarked that this sign is only granted to the Tzadik of the generation.

When the Choze passed away, the Apter and R. Yitzchak Meir were once again sitting in the Sukkah and the name of Y-H-V-H appeared on the Schach. 

The Apter Rav said: “We asked the Master of the Universe that He should give this to us.”
