This chapter examines how the Buddhist-derived Samboilbae and Ochetuji rituals, used in the 10.29 Itaewon disaster movement, highlighted the significance of death and the value of life for participants. Through the physical challenges of these rituals, participants not only commemorated the victims but also formed deep emotional connections with the victims and bereaved families. This experience led to a profound realization about the importance of life and death, motivating participants to actively pursue the collective ideals of respecting life and creating a safer society. Additionally, these rituals served as a transformative process in which participants abandoned their previous social identities, values, and ways of life, thus adopting new roles as subjects of the social disaster movement. The visibility and materiality of Samboilbae and Ochetuji enhanced their effectiveness in public engagement and media representation, inviting the audience into the emotions and experiences of the participants. This resulted in greater solidarity with the bereaved families’ calls for justice and safety, forming a community of remembrance and shared commitment to address it together.
