佛說仁王般若波羅蜜經 1.49

1.49

"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.
