A rite of passage is a ceremonial event that marks a change in a persons life. It is a ritual that occurs when an individual leaves one group to enter another, and it involves a significant change of status in society. Rites of passage have three phases: separation, liminality, and incorporation, as described by Arnold van Gennep. The three phases are:

1. Separation: This is the first phase of a rite of passage, where the individual is separated from their previous status or identity. This can be a physical or symbolic separation, such as leaving home or changing clothes.

2. Liminality: This is the second phase of a rite of passage, where the individual is in a state of transition and is neither in their old status nor in their new status. This phase is often marked by rituals or tests that challenge the individual and help them to develop new skills or perspectives.

3. Incorporation: This is the final phase of a rite of passage, where the individual is reintegrated into society with their new status or identity. This phase often involves a celebration or ceremony that recognizes the individuals new status and welcomes them into their new community.

Rites of passage are universal and have been found in all historically known societies. They can be connected with biological milestones, such as birth, maturity, reproduction, and death, or they can celebrate changes that are wholly cultural, such as initiation into societies composed of people with special interests. Rites of passage are diverse and can be found throughout many cultures around the world.
