Keep a Low Profile Group members should neither speak about nor publicize this holy group, its ways and activities. They should not boast about it before others. God said of the second set of the Ten Commandments—the set which lasted— that “there is nothing finer than concealment” (source). The holy Zohar was revealed in the cave of Rabbi Shimon bar Yochai and in the wilderness, secretively. The entire Kabbalah is called a “secret.” So also, any service of God that involves a revelation of your spirit stands in opposition to tumult and publicity, and finds concealment congenial. “Hashem is not in the uproar” (Kings I 19:11).

But if someone wants to join, accept him warmly, and tell him about the group—as long as it is clear to you that his intent is for the sake of heaven. Also, you may propose to someone that he join the group if you see that his inclusion would benefit both him and the group. (Just be sure that you yourself have no ulterior motive.)
