Qualitative research in the form of case studies uses interpretive methods. Data collection through observation and interviews. Associative and dissociative patterns of social interaction became the theory of analysis. Data analysis includes presentation, reduction, and verification. The results showed the pattern of social interaction by the Sunda Wiwitan community in building harmony between religious people in Cigugur using associative interaction patterns. The existence of this associative intercation pattern in the realm of praxis is embodied through several strategies. First, build an attitude of religious tolerance. Second, build an attitude of openness (tepo seliro). Third, build cooperation between religious believers. Fourth, establish dialogue among religious people.
