Why do they throw a plate in the grave of a greek orthodox burial?

In Greek Orthodox burials, it is customary to throw a plate into the grave as a symbolic gesture representing the act of honoring the deceased. The plate, often unbreakable, signifies a farewell and is a way for mourners to express their love and respect. This practice reflects the belief in the continuity of life and the importance of community in the grieving process. It also serves as a reminder of the shared memories and relationships with the departed.
