This study has focused on the mystical experience which is one of the most important topics of psychology of religion, but it is a subject not examined enough in Turkey and also tried to determine the relationship between personality traits and personality. Data were collected from 345 students who were studying at Erciyes University Faculty of Theology by questionnaire method. “The Mysticism Scale”which is developed by Ralph Hood and widely used in international literature to measure the mystical experience and “HEXACO (...) Personality Inventory”were used to measure the personality traits of students. In addition to descriptive statistics of demographic characteristics of the sample, The Pearson Moments Multiplication Correlation Analysis, Independent Sample t-Test and One-Way ANOVA techniques were used in the analysis. Findings show that participants have the highest average to Positive Affect and the lowest average to Temporal/Spatial Quality factor. In addition, they obtained close values in Ego Quality, Noetic Quality and Ineffability factors. When the students were evaluated in terms of gender, it was seen that there was a difference in level of significance only in terms of Unifying Quality. ANOVA analysis was carried out to determine whether there was any variation in class variable. As a result of this analysis, it is seen that all of the factors are significantly differentiated in terms of class variable. There is no difference in level of significance between age and mystical experience factors, the last independent variable. When looked at the correlations among mystical experience factors, it is understood that all of the factors are in a meaningful relationship with each other. Among the six factors of HEXACO, the students have the highest average on Humility-Honesty; the lowest average on eXtraversion. In terms of gender, there is a statistically significant difference in the level of Humility-Honesty, Emotionality, and Conscientiousness. There is no significant difference between class and age variables and personality traits. According to Linear Regression analysis, Agreeableness, Conscientiousness and Openness to Experience factors of personality traits are predictive of mystical experience in a statistically significant level. Summary: The fact that the mystical experience is a repetitive phenomenon in different social, cultural and religious structures in different periods and has a mysterious element in it has caused that mysticism has taken its place among the basic subjects of the field since the first periods of psychology of religion. One of the sections of The Varieties of Religious Experience, which is regarded as the main source of the area, is mysticism. In general, "mystical experience" is considered as a subcategory of "religious experience", which is a wider area. For this reason, it also carries the characteristics of religious experience. Due to these common features, it can be seen that they are used in place of each other in the literature.If the religious experience is defined as the experience of the individual at the time of encounter with the sacred, such experience can be obtained in two ways. In the “religion-based mystical experience”, which is the first way, institutional or established religious thoughts and understandings and holly writings are influential. The second way, “non-religious or natural mystical experience”, can be said to be spiritual quests that individual needs play an important role in them are effective.Personality is used as one of the basic variables in social and health sciences in general, and in psychology because it is among the main subjects in particular. The common emphasis of research on personality is that the phenomenon is extremely complicated. Despite its widespread use, the abstraction of the concept has been influenced by the diversity of the researchers' perspectives and this has led to a lack of clear consensus on the definition. However, in order to investigate the phenomenon in recent periods, dimensional approaches that their basic assumption is personality can be categorized under certain factors have begun to be preferred. In this study, HEXACO was used, because it was thought that it could make a more detailed measurement of personality.The sample of this study is composed of 345 students studying at Erciyes University Theology Faculty in 2017-2018 academic year. When looked at the gender distribution of the sample, the rate of male students was 21.2% (n=73); and the rate of female students was 78.8% (n=272). This reflects the current situation in the faculty. The average age was 21,13 (sd=1,761). The age range is 18-26. Class distribution was 23,5% (n = 81) in Preparatory class; 15.4% (n = 53) in first-grade; 19.4% (n = 67) in second-grade; 18.3% (n=63) in third grade (n = 63); and 23.5% (n = 81) in the fourth grade. It has been noted that distributions are homogeneous in terms of class variables.The "Mystical Experience Scale" which is developed by Ralph W. Hood to measure the criteria which are offered by Walter T. Stace and which must be in the mystical experience has been used in determining the tendency of mystical experience. Hood et al. have reported reasonable reliabilities for subscales based on 3-factor solution. Alpha coefficients of the original scale were,76,,69, and,76 for the extrovertive mysticism, introvertive mysticism and religious interpretation respectively. The adaptation of the scale to Turkish culture and the validity and reliability study were carried out by Mehmet Süheyl Unal as a graduate thesis and it was stated that the Alpha coefficient was,89. In this study, the Cronbach Alpha reliability coefficient of scale is,91. HEXACO, developed by Lee and Ashton, was used to determine personality traits. The scale was adapted to Turkish by Wasti, Lee, Ashton and Somer. The scale consists of Honesty-humility (H), Emotionality (E), eXtraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to experience (O) factors.Pearson Moments Multiplication Correlation Analysis was performed to determine if there is a relationship between mystical experience tendencies and personality traits when the data were analyzed in accordance with the aim of the study. Later, it was tried to determine the power of explaining the variables with Multiple Linear Regression Analysis. In addition, One-way ANOVA was used to determine whether there was any relationship between significance levels. Moreover, descriptive statistics of relevant variables are included in the study.Findings show that participants have the highest average to Positive Affect (m=3,69; sd.=,77) and the lowest average to Temporal/Spatial Quality (m=2,94; sd.=,89) factor in terms of mystical experience. Additively, they obtained close values in Ego Quality, Noetic Quality and Ineffability factors. When the students were evaluated in terms of gender, it was seen that there was a difference in level of significance only in terms of Unifying Quality (t=1,770; p=,028). ANOVA analysis was carried out to determine whether there was any variation in class variable. As a result of this analysis, it is seen that all of the factors are significantly differentiated in terms of class variable. From the standing point of class variable, it is seen that the first grades differed negatively compared to the other classes. According to the data, the scores on the mystical experience scale for preparation and first grade are high while the averages for the next grade are falling. There is no difference on level of significance between age and mystical experience factors, the last independent variable. When looked at the correlations among mystical experience factors, it is understood that all of the factors are in a meaningful relationship with each other. The highest correlation is between Religious Quality and Ineffability (r=,661); the lowest correlation is between the Unifying Quality and the Temporal/Spatial Quality (r=,346).Among the six factors of HEXACO that have been developed to determine the personality traits, the students have the highest average on Humility-Honesty (m=3,76; sd.=,55); the lowest average on eXtraversion (m=3,04; sd.=0,65). In terms of gender, there is a statistically significant difference in factors of Humility-Honesty (t=,606; p=,004), Emotionality (t=,334; p=,000), and Constientiousness (t=,022; p=,033). There is no significant difference between class and age variables and personality traits. According to Linear Regression analysis, Agreeableness, Constientiousness and Openness to Experience factors of personality traits are predictive of mystical experience in a significant level statistically.Personality dimensions that are most related to mystical experience as a result of analysis are Conscientiousness and Openness to Experience. When the mystical experience is compared with the personality traits, it is concluded that Openness to Experience factor is related to all the factors of the mystical experience except for the Ineffability. Although the relationship is regarded as weak in terms of correlation, it is an important finding that there are positive relations in between. In other words, as personality traits evolve, the mystical experience level also increases. The lack of a similar work in the literature in this respect removes the possibility of making comparisons.
