The Zhengfa Yanzang (HànyàPënyën: ZhèngfàYÃÂnzàng; Rà Âmaji: Shà Âbà Âgenzà Â), known in English as the Treasury of the Correct Dharma Eye or by the Japanese reading of its title, Shà Âbà Âgenzà Â, is a collection of gong'ans (kà Âans in Japanese) compiled by Dahui Zonggao. Dahui was a famous popularizer of gong'ans during the Song dynasty in China. Dahui's collection is composed of three scrolls prefaced by three short introductory pieces. Dahui's work uses the same Chinese characters for its title as the now well known Shà Âbà Âgenzà  written by the Japanese monk Eihei Dà Âgen in the thirteenth century. Upon arriving in China, Dà Âgen first studied under Wuji Lepai, a disciple of Dahui, which is where he probably came into contact with Dahui's Zhengfa Yanzang. In his book Dogen's Manuals of Zen Meditation, the modern scholar Carl Bielefeldt acknowledges that Dà Âgen likely took the title from Dahui for his own kà Âan collection, the Shinji Shà Âbà Âgenzà Â, and kept it for his later and now most well-known work, the Kana Shà Âbà Âgenzà  (usually referred to simply as "the Shà Âbà Âgenzà Â"): <blockquote> Indeed the fact that Dà Âgen styled his effort "Shà Âbà  genzà Â" suggests that he had as his model a similar compilation of the same title by the most famous of Sung masters, Ta-Hui Tsung-kao Dahui Zonggao.</blockquote>
