Throughout history, humanity has tried to explore the depths of the universe and the human soul, attracted by the allure of the unknown. This desire for discovery has not only remained within the boundaries of concrete sciences; it has also extended to unseen, mysterious and metaphysical dimensions. "Secret Sciences" or more commonly known as "Occultism and Esotericism" is a reflection of this search.
 
This discipline, which has existed from ancient times to the present day, has been accepted as a means of enlightenment for both the secrets of the universe and for man himself through supernatural powers, ancient symbols, esoteric knowledge and mystical practices. Occultism is not an ordinary belief or a simple set of practices; on the contrary, it offers a deep accumulation and cultural interaction in a wide range from mythology to philosophy, psychology to theology. This field includes many sub-branches such as Hermeticism, alchemy, astrology, magic, tarot and spiritualism, and has also been a subject of discussion in the academic world from time to time.
 
This accumulation of knowledge, especially those outside of modern scientific paradigms, has been both criticized and intrigued. The appeal of occult sciences does not only stem from their mystical and esoteric aspects. At the same time, these disciplines have had a profound impact on art, literature, politics and science throughout history. For example, alchemical studies during the Renaissance not only formed the cornerstones of chemistry; they also shaped the philosophical and aesthetic understanding of the period. Astrology began as a branch of science aimed at understanding the sky, but over time it has shown a wide cultural spread as a means of interpreting individuals' destinies.
 
This encyclopedia aims to provide a broad perspective from the origins of occultism and mysticism to their current effects. Our aim is not only to compile basic information about this field; but also to examine the historical, cultural and philosophical context of occult sciences and to approach this discipline in a multidimensional way. We aim to analyze in detail the deep meanings behind esoteric symbols, the psychological and social functions of rituals, and the forms this discipline has taken in different geographies and periods.
 
Our goal is to share this information; however, we never accept its use for negative or malicious purposes. The studies to be conducted should definitely and definitely contribute to oneself and society first, and should be based on the principle of not harming any living being while doing so. On the other hand, no study in this work can replace medical treatment. Therefore, the information in the book should never be used instead of professional medical treatment. A strong belief system can create a positive mood in some people, but this is not scientific evidence. As a result, every study to be conducted on these subjects is both a quest to discover the unknown and a journey into the cultural heritage of humanity. This encyclopedia invites its readers to this mysterious world and encourages them to open a door to the fascinating universe of ancient knowledge. Occult sciences are not only a part of the past; they continue to exist as a way of searching for meaning in today's complex world. Now, it is time to embark on a journey together towards this ancient treasure of wisdom.
