[265] How is there knowledge (ñāṇa) of suffering (dukkha), knowledge of the origin of suffering, knowledge of the cessation of suffering, and knowledge of the way of practice leading to the cessation of suffering? For one endowed with the path (magga), there is knowledge: this very knowledge is knowledge of suffering; this very knowledge is knowledge of the origin of suffering; this very knowledge is knowledge of the cessation of suffering; this very knowledge is knowledge of the way of practice leading to the cessation of suffering.
