The classical Taoist philosophical treatise "tao Te Ching" (Iv.iii centuries B.c.) is a foundational source of the doctrine and an outstanding monument of Chinese thought, where elements of Daoism are expounded, which greatly influenced not only the culture of China, but that of the entire world. It is attributed to the founder of Daoism, Old Chinese philosopher Laozi. At the heart of this work is the doctrine of the great Dao, amorphous and speechless, prevailing in everything everywhere, always and interminably.
