The Philosophy of Harmony offers a holistic approach to understanding reality and serves as a guide for living a good life. Harmony, as the highest principle, is the key to a coherent worldview that comprehends the diversity, complexity, and contradictions of the universe in an absolute unity. Everything in the universe strives for harmony. A deliberate alignment or conscious pursuit of harmony leads to a life of balance, inner peace, and fulfillment. In a world that is far from being in harmony, it is all the more important to develop ideals that can provide guidance, orientation, and meaning, both individually and collectively.The texts in this book were written with the help of ChatGPT.
