Lineage

Though Dogen emphasised the importance of the correct transmission of the Buddha dharma, as guaranteed by the line of transmission from Shakyamuni, his own transmission became problematic in the third generation. In 1267 Ejō retired as Abbot of Eihei-ji, giving way to Gikai, who was already favored by Dōgen. Gikai introduced esoteric elements into the practice. Opposition arose, and in 1272 Ejō resumed the position of abbot. Following Ejō's death in 1280, Gikai became abbot again, strengthened by the support of the military for magical practices. Opposition arose again, and Gikai was forced to leave Eihei-ji. He was succeeded by Gien, who was first trained in the Daruma-school of Nōnin. His supporters designated him as the third abbot, rejecting the legitimacy of Gien.

Jakuen, a student of Rujing, who traced his lineage "directly back the Zen of the Song period", established Hōkyō-ji, where a strict style of Zen was practised. Students of his played a role in the conflict between Giin and Gikai.

A notable successor of Dogen was Keizan (瑩山; 1268–1325), founder of Sōji-ji Temple and author of the Record of the Transmission of Light (傳光錄 Denkōroku), which traces the succession of Zen masters from Siddhārtha Gautama up to Keizan's own day. Together, Dōgen and Keizan are regarded as the founders of the Sōtō school in Japan.
