The Buddha teachings are the exhaustive studies of the Absolute Truth; Words of Buddha follow the mind. Buddhadharma thus centers around the Mind-only. The Avataṃsaka Sutra says, “The three realms are mind-only,” “You should contemplate the nature of the Dharma Realm. Everything is made from the mind alone.” The world of sentient beings and the container world are made from the mind only. Even the Ten Worlds and Six Realms do not go beyond the mind. The Mind-only is especially emphasized in the Avataṃsaka Sutra. Dharma is mind-only. All phenomena are nothing but consciousness. All is made from the mind, and all does not exist without the mind. That is the development of this central philosophy, “Dependent Origination is mind-only.” The Huayan School was named after the Avataṃsaka Sutra, or Huayan Jing. According to the sutra, “All in the three realms is nothing more than one''s mind.” All beings and phenomena are created and done by the mind; The idealism of human agency has greatly shaped the development of Huayan School’s philosophy of the Mind-only.
