The word "Shiva" has different meanings across different cultures. In Judaism, Shiva is the first period of structured mourning and refers to a seven-day period of formalized mourning by the immediate family of the deceased. The primary purpose of the Shiva tradition, or "sitting Shiva," is to create an environment of comfort and community for mourners, helping guide friends and family members through the loss of a loved one. Throughout the weeklong Shiva period, mourners come together in one family’s home to offer their condolences and support. Specific observances may vary depending on the Jewish community and its beliefs. From a practical standpoint, the Shiva process and practices associated with Jewish mourning add structure to the life of a mourner following a death.
