Metaphysics is said to be a philosophy that pursues the fundamental principles of existence. We think that it is to pursue the essence and truth beyond the boundaries of science and non-science, matter and non-material. At present, we define the essence that we think of as "a world in which one feels beautiful and is filled with the joy and gratitude of living." There is no definition of this beauty, the joy of living, or the expression of gratitude, neither being material nor non-material. That is why we want to express, embody, and convey joy and healing to people by making full use of design, photography, images, drawings, words, and sometimes technology. That is the mission of expressive artists.
