Abstract
The purpose of this study was to investigate the relationship between healthy spirituality and two important concepts in positive psychology, sense of authenticity (SOA) and flow experience, with the addition of sense of coherence (SOC). The SBAS-TEST, Sense of Authenticity Scale (SOAS) and Flow Experience Check List were administered to 211 college students in the metropolitan Tokyo area. The results snowed high correlation of authenticity with spiritual behavior (Will) (r=0.49, p<0.001) and spiritual attitude (Joy) (r=0.65, p<0.001) but no relation with spiritual sense (Sense). The relation of SOA with healthy spirituality is the same as the relation between SOC and healthy spirituality. Flow experience has high correlation with all three domains (Will, Joy and Sense) of healthy spirituality. This means that the status of healthy spirituality can be explained as becoming our true self united with authentic non-local consciousness, and that healthy spirituality contributes to psychological growth and general health.
