Editing Dōgen (section)

===Early training===
In 1212, the spring of his thirteenth year, Dōgen fled the house of his uncle [[Matsudono Moroie]] and went to his uncle Ryōkan Hōgen at the foot of [[Mount Hiei]], the headquarters of the [[Tendai|Tendai school]] of Buddhism.<ref name=":7" />  Stating that his mother's death was the reason he wanted to become a monk, Ryōkan sent the young Dōgen to [[Jien]], an abbot at Yokawa on Mount Hiei.<ref name=":7" /> According to the ''Kenzeiki'' ({{lang|ja|建撕記}}), he became possessed by a single question with regard to the Tendai doctrine:
{{blockquote|As I study both the exoteric and the esoteric schools of Buddhism, they maintain that human beings are endowed with [[Buddha-nature|Dharma-nature]] by birth. If this is the case, why did the [[Buddha (general)|Buddhas]] of all ages — undoubtedly in possession of [[Bodhi|enlightenment]] — find it necessary to seek enlightenment and engage in spiritual practice?<ref>{{harvp|Bodiford|2008|p=22}}</ref><ref>{{harvp|Ōkubo|1966|p=80}}</ref>}}

This question was, in large part, prompted by the Tendai concept of [[Hongaku|original enlightenment]] ({{lang|ja|本覚}} ''hongaku''), which states that all human beings are enlightened by nature and that, consequently, any notion of achieving enlightenment through practice is fundamentally flawed.<ref>{{harvp|Abe|1992|pp=19–20}}</ref>

The ''Kenzeiki'' further states that he found no answer to his question at Mount Hiei, and that he was disillusioned by the internal politics and need for social prominence for advancement.<ref name="Bodiford_22_36"/> Therefore, Dōgen left to seek an answer from other Buddhist masters. He went to visit Kōin, the Tendai abbot of [[Mii-dera|Onjō-ji Temple]] ({{lang|ja|園城寺}}), asking him this same question. Kōin said that, in order to find an answer, he might want to consider studying [[Chan Buddhism|Chán]] in China.<ref>{{harvp|Tanahashi|1997|p=4}}</ref> In 1217, two years after the death of contemporary Zen Buddhist [[Eisai|Myōan Eisai]], Dōgen went to study at [[Kennin-ji|Kennin-ji Temple]] ({{lang|ja|建仁寺}}), under Eisai's successor, Myōzen ({{lang|ja|明全}}).<ref name="Bodiford_22_36"/>
