A reverent and searching meditation on the Temple Mount, this book unites halakhic rigor, rabbinic memory, and mystical vision in a luminous study of sacred space. Moving through Mishnah, Talmud, Maimonides, later decisors, and the hidden language of Kabbalah, it traces the boundaries of holiness, the laws of purity, and the fraught question of ascent in our time. At its heart stands the Foundation Stone, imagined as the axis of creation and the echo of the Holy of Holies, alongside memories of the Ark and hopes for redemption. Learned yet fervent, it becomes not only a guide to law and sanctity, but a stirring portrait of Jerusalem as the meeting place of longing, awe, and covenant.
