Such groups often use a series of carefully designed psychological tactics to link physical pain with the "purification" or "ascension" of the soul. The following are possible mechanisms and processes: 1. Creating emotional dependence and identity • The group will deliberately create an "ultimate truth", claiming that only by experiencing physical pain can one get rid of the inner filth and sin and achieve a higher level of harmony with the divine existence. • Through collective rituals and group activities, members are emotionally bound to the group, strengthening the identity of "we are different from the outside world" and enhancing group cohesion. 2. Psychological indoctrination and belief reshaping • Adopting slogans such as "suffering is salvation" and "purification rituals" to repeatedly emphasize the legitimacy and necessity of physical suffering. • By cutting and filtering information - such as specially selecting those seemingly "miraculous" cases or experiences, it is implied that hard work will lead to self-salvation and soul ascension. • Using intimidation and guilt: claiming that if members do not experience or refuse pain, they cannot truly purify their souls and may even suffer eternal spiritual punishment. 3. Ritualized physical practice • Designing self-flagellation, fasting, extreme physical labor or other physical training as sacred rituals, so that members can personally experience the "pain of purification" in the rituals. • In these rituals, pain is programmed and sanctified, and members are often told that this is a "trial" or "test", and through this setting, they strengthen their understanding of the positive meaning of pain. 4. Social isolation and information control • Deliberately isolate members from the outside world to prevent rational or questioning voices from the outside world, so that members are more dependent on the group's way of interpreting the world. • Suppress or marginalize those who doubt or resist, and create an image of "apostates" or "sinners", so as to force members to believe that only by experiencing pain can they prove their loyalty to the truth. 5. Dual manipulation of emotions and cognition • Using group pressure and the emotional agitation effect generated in collective rituals, individuals lose their self-judgment in collective enthusiasm, so that they are more likely to accept the concept of "pain is purification". • Using cognitive dissonance theory, the ordinary suffering in members' daily lives is rationalized and reconstructed into a sacred trial, and their cognition of the meaning of physical pain is gradually changed. In short, this kind of group uses organizational, ritualistic and emotional means to make individuals gradually agree and firmly believe that only through physical pain can the soul be "purified" and elevated. This is not only a process of shaping faith, but also a strategy to make the individual's inner world gradually consistent with the group's doctrine through psychological and social control.
