Q. There is a segula to have 40 women davening together with specific people in mind as they take Challah from their dough with a bracha. Can one be part of two groups of 40 with the same Hefresh Challah dough (davening for two people)? Similarly, if one is part of a Tehillim group, saying specific perakim of Tehillim so that the group as a whole complete the whole Sefer Tehillim, can one say their specific Perakim of Tehillim and have two sets of names in mind? Thank you.
A. Sefer Shailas Rav (1,21), quotes in the name of Rav Chaim Kanievsky Shlit"a that when asked about this particular Challah Segulah, he responded that he was not aware of it.
Horav Shlomo Miller's Shlit"a advice is, that all Tefilos, recitals of Tehilim and segulas, without endorsing any one Segula in particular, should be said for all Cholei Isroel. He added that the main purpose of a Segula is to inspire and uplift the Kavana of Tefilah, but it is prayer what actually helps.
