This chapter features the case study of a Malaysian-Chinese blogger, Stark, who after migrating, blogged about her spiritual experiences back in Malaysia, including her conversion to Christianity and the subsequent estrangement from her parents. Through analysing this intersection of religion, the internet, and migration, the notion of authenticity in the practice of online religion can be explored. Online authenticity is a difficult element to measure, and is made more complicated when applied to a subjective matter like spirituality. The case study will demonstrate that the act of blogging serves the purpose of heritaging, spiritual catharsis, and communication with her parents, and thus infer a genuine spiritual activity that contributes to her still-developing religious identity.
