"The Denkōroku", "The Record of the Transmission of the Light", written by Keizan Jōkin 瑩山紹瑾 (1268–1325), is an example of the "Transmission of the Lamp" genre. It contains literary accounts of the patriarchs of the Soto-lineage, from Shakyamuni Buddha to Koun Ejō, in which kensho plays a central role. They are not to be taken as literal accounts of awakening, but as stories underpinning the legitimacy of the Dogen-shu, which in its early history had seen a fierce internal conflict over the correct lineage during the Sandai sōron.
