Since ancient times, people have described earthly reality on a four-part principle: four cardinal points, four seasons, four elements. The system of knowledge about the four elements is closely intertwined with astrology, esotericism and the doctrine of tarot (four suits of the Younger Arcans). According to ancient sources, each element has its own unique effect on a person's personality. In the pages of this book, Fire, Water, Air and Earth are images that have been used since ancient times to describe the four main types of human individuality.
