群生昏寢，長夜冥冥。先覺警世，慧日赫赫。故《西域記》明四日照世：東有馬鳴，南有提婆，西有龍猛，北有童受；或通宗乎眾典，或別釋於一經。既分照乎四方，乃俱破於群翳，故今此集列論主焉。

All living beings slumber in ignorance throughout the dark, long night. The first to awaken alerted the world, with the sun of wisdom blazing brilliantly. Thus the Xiyu ji explains that four suns illuminated the world: in the east was Aśvaghoṣa, in the south was Āryadeva, in the west was Nāgārjuna, and in the north was Kumāralāta; some penetrated the tenets of the myriad scriptures, while others separately commented on a single sūtra. Having divided their illumination across the four directions, they collectively destroyed all obscurations; therefore, in this collection, the masters of treatises are now listed.
