Dharma transmission
This precept-transmission has a long history in Sōtō-shu. Keizan, the fourth Sōtō-patriarch, received transmission of the precepts from Gien, the third (actually fourth) abbot of Eihei-ji, but received dharma transmission from Tettsū Gikai, the disputed third abbot of Enheiji. According to Keizan's Denkoroku, Dogen had received Dharma transmission from Rujing, bur precept transmission via the Rinzai-linegae of Myozen, with whom he first studied.
