In his sefer, Darash Moshe, Rav Moshe Feinstein ztz”l connects the parallel calendar dates of Motzaei Tishah B’Av and the night of Kol Nidrei. In general, my rebbi Rav Moshe Shapira was aghast at the culture of our generation where every few months a new segulah becomes fashionable. Rav Moshe argued that once the Zohar revealed the power of pesichah, anyone with proper kavanah can tap into the moment. Rav Moshe Sternbuch shlita shared that a powerful segulah for childbirth, especially for those who have experienced miscarriages, is to have kavanah on the word chayim, which means life. The golden key in Rome, mirrored in our people’s reverence to pesichah, unlocks a portal to that eternal world of chayim.
