Background: If vegetative life carries a vegetative soul, and rational life a rational soul, what does spiritual life carry? What are the differences between a spiritual and rational soul? Can a spiritual soul somehow touch and see, can it be subjected to scientific experiments? What is hagiotherapy? Why is lack of faith a defect in spiritual terms? What happens in people who believe? The aim of this paper is to answer these questions and also explain spiritual abilities or power - faith in terms of hagiotherapy, how it affects a person's life and work, and also society.
Cases and methods: We will be relying on the most important and recently published scientific books from the founder of hagiotherapy, Tomislav Ivančić, PhD, titled Hagiotherapy Encountering Man, Man's Total Woundedness, Hagiotherapeutic Anthropology, but also an older booklet titled "Spiritual Life in the Prayer and Word Community".
Results: We will discover the meaning of hagiotherapy in this paper - therapy for that part of a person which has not been previously therapeutically investigated and which poses a challenge to the contemporary world. We have found that the spiritual soul, specifically a person's specificity, carries in it a mechanism affecting the brain's functioning, and also a person's complete psychophysical existence. The investigation reveals that a person who has faith, where faith is a power or ability of the spiritual soul in terms of hagiotherapy, acquires an amazing perspective, develops entirely and expects goodness, creates projects for the future and is directed with great reverence to creating a spiritual reality in the psychophysical world. Not believing means being broken, void of strength and will power, tied to the "now", and depressed.
Conclusion: Based on this research, it seems that hagiotherapy offers new perspectives in resolving the difficulties of human existence, on a personal and global level. The person who believes, always moves forward, discovers new worlds, is ahead of their time and a leader of their generation. Hagiotherapy evidently wants to be a return to a person's true values and a proven path towards a good future.
