The study of Saadi love, based on the theory of existential psychotherapy by Ervin Yalom

Significant expansion of communication models and networks; Also, the diversity of biological and cultural needs has caused the disappearance of the contractual boundaries of disciplines and sciences, especially the humanities. Today, due to the increase in psychological problems and rising suicide rates, human beings need methods to use it to increase the psychological capacity of people. Therefore, to help theorize in disciplines such as psychotherapy, we need to use sciences such as literature; because literature-based psychotherapy can provide good services to psychotherapy due to its educational, moral and religious teachings. Saadi, a great thinker who has become world famous for her expression, moral wisdom and philosophical wisdom, has expressed the true connection and meaning of love in her works. In the present study, with descriptive-analytical methods, based on interdisciplinary studies, love in Saadi's thoughts has been studied with the approach of Yalom Existential Psychotherapy. The main purpose of the research is to answer the question of how Saadi and Yalom help human beings, through love and communication with others, to cope with their existential loneliness in life or to free themselves from it. Findings show that despite the cultural differences and temporal-spatial dimension, both thinkers have expressed their relationship with each other through "needless love" in almost the same language and manner.
