Judaism looks upon mourning as a process by which the stricken can re-enter into society, and so provides a series of customs that make this process gradual. The first stage, observed as all the stages are by immediate relatives (parents, spouse, siblings and children) is the (literally meaning "seven"), which consists of the first seven days after the funeral. The second stage is the (thirty), referring to the thirty days following the death. The period of mourning after the death of a parent lasts one year. Each stage places lighter demands and restrictions than the previous one in order to reintegrate the bereaved into normal life.
