A Time of Favour

The Be'er Hachaim [Chanukah, p 125] writes:  ''The Zohar [206a] teaches that whenever the Aron HaKodesh is opened it is an Eis Ratzon [a time of favour].  We have a direct kabbalah from the Tzemach Tzedek, who heard from his grandfather the Ba'al HaTanya, who heard from . his Rebbe, the Maggid of Mezeritch, who heard from his own Rebbe, the Ba'al Shem Tov, that all prayers and supplications that are uttered when the Aron is open will be fulfilled in part or in full.

Many students of the Ba'al Shem Tov testify that at that moment the gates of compassion are opened and great things can be accomplished.
