Purpose: The purpose of this research was to provide a model for predicting time series of financial information based on the Lyapunov representation of information using chaos theory.Method: This research is applied in its purpose, which is conducted using a quantitative approach. The research ranks as descriptive-causal accounting research based on actual information in companies' financial statements. The research method is the "post-event" type and was carried out using chaos theory and Saida's method based on the Lyapunov view.Findings: The findings showed that during the ADF test, the null hypothesis was rejected at a level of less than 5% type 1 error and 95% confidence, and it shows that the data is not static. During the substitution analysis test and its significance level, the behavior of the time series of the main financial information is significantly different compared to their substitutes. The obtained value was calculated to describe the production process of all data sets for μ = 2, ApEnMax equal to 0.65 and rMax equal to 0.32, and for μ = 3, ApEnMax equal to 0.6 and rMax equal to 0.44. The value of the Lyapunov profile in stability at a certain point is less than zero and in the limited cycle of stability is equal to zero and in chaos, it is greater than zero and smaller than ∞, and in noise it is equal to ∞.Conclusion: The results show that higher returns, encourage investors to invest and increase the flow of capital. It is believed that companies' stock returns are a function of systematic risk, and systematic risk represents the changes in the return rate of a share compared to the changes in the return rate of the entire stock market.

When deliberating on the spiritual dimension of tourism, one key question is that how individuals are seeking for their life meaning and experiences of divine existence, as well as their connectedness as subjectively lived during their travel.  In fact, tourism is closely connected to religion which has always been a powerful travel motivation from the time of early pilgrimages to contemporary journeys to sacred places. Religious sites, rituals, festivals and ceremonies are considered important attractions for both religious followers with special systems of belief and tourists with a casual interest. Perhaps, this characteristic of the tourism experience is the main reason for spiritual tourism experiences being recently popular among individuals who have started engaging in spiritualitydriven experiences and among persons aiming to develop their continuing sublime engagement by means of travel. There are various reasons for travelling for spiritual growth which is opposed to the traditional notions of pilgrimage and religious tourism. However, relatively few scholars have explored the multitudinous relationships between religion, spirituality, and sustainable tourism, despite the pervasiveness of religious tourism and spiritual connections to place. A subject that has received only scant attention in the literature is the negative social and ecological impacts of religious (mass) tourism. Several authors have noted the negative impacts of religious tourism on the commercialization of places and artifacts that were once held as sacred locations. The commodification of religious symbols and the economic implications of selling them should become of increased interest to researchers as the world becomes more consumption-oriented.
