The "Da Fang et al. Collection of Sutras" is an important classic in the field of Buddhism. It brings together the essence of various Mahayana sutras, so it is called "The Collection of Sutras" for short. This classic mainly expounds the six paramitas of the Mahayana and the idea of the emptiness of all dharmas, which is the core teaching of Buddhist practice and liberation. At the same time, it also contains some esoteric teachings, showing the diversity and richness of Buddhist practice. In this classic, we can see descriptions of demons, asuras and other heavenly protectors. These contents had a profound impact on the later development of Buddhism and gave birth to the idea that demons and Buddhas are one and the same. This idea emphasizes the interdependence and transformation of Buddha and demons, providing a broader perspective for Buddhist practice and liberation. In addition, the "Dafang et al. Collection of Sutras" also predicts the subsequent divisions of Buddhism and talks about how disciples can respectively accept and uphold the Tathagata's twelve sutras. This provided a classic basis for the diversity and development of Buddhism later.
