Spiritual intelligence and emotional intelligence can complement each other for purification of human life. On the one hand, spiritual intelligence strengthens spiritual and religious beliefs, thus establishing good qualities. On the other hand, emotional intelligence can improve social relationships, control emotions and help individuals progress towards perfection. This was a descriptive-correlational research where the sample size was estimated to be 424 students at Isfahan University of Medical Sciences selected through multistage cluster sampling. The measurement tools involved Trait Emotional Intelligence Questionnaire (TEIQue) developed by Petrides and Furnham (2003) and self-administered questionnaire for spiritual intelligence, whose reliability levels were calculated to be 0.84 and 0.87, respectively. The data were analyzed through multiple regression analysis. According to the regression analysis, the findings suggested that there is a relationship between spiritual intelligence and emotional intelligence. This relationship was observed in various dimensions of spiritual intelligence and emotional intelligence, between which a relationship was identified by the current study. Spiritual intelligence leads to more emotional intelligence; i.e. emotional intelligence strengthens spiritual intelligence.
