 In the preface to this text, there is a line (“Even the sound of the winds, the cry of the crane, the cackle of fowl and the barking of dogs – all may be written” [Mair, 733]) that is derived from a Sung scholar (Cheng Ch’iao) that “praises the phonological sophistication of the Buddhist monks.” The fact that Sejong was a devout Buddhist could possibly also be seen as evidence of the Buddhist influence on printing.All but two of the earliest texts using Sejong’s Hunmin chong um were Buddhist texts.Also, Hunmin chong um is based partly on Phags-pa that can be traced back to Srong-brtsan-sgam-po, the king who introduced Buddhism to Tibet.
