佛說仁王般若波羅蜜經 1.49

1.49

「大王！法輪者：法本如、重誦如、受記如、不誦偈如、無問而自說如、戒經如、譬喻如、法界如、本事如、方廣如、未曾有如、論議如，是名味句音聲果文字記句一切如。若取文字者，不行空也。

"Great King! As for the wheel of Dharma: sutras are suchness, gāthās are suchness, vyākaraṇas are suchness, geyas are suchness, udānas are suchness, vinayas are suchness, avadānas are suchness, itivṛttakas are suchness, jātakas are suchness, vaipulyas are suchness, adbhutadharmas are suchness, and upadeśas are suchness. These are called expressions, phrases, sounds, fruits, letters, predictions, and sentences, all of which are suchness. If one grasps at words and letters, one does not practice emptiness.
