Today the word ‘invisible’ is often taken to mean ‘non-existent’. But for the ancient Egyptians, the invisible was the cause of the visible and therefore, in a sense, more important. They realized that the form of a person, what they wear and how they appear is o nly a reflection of something internal which we cannot see. And likewise that the things that are most important to us, such as life and death, justice, thoughts, and feelings, are all invisible. So they dedicated their civilization to a profound investigation – and living experience of the invisible side of life.
