Among the writings attributed to Dōgen, one text stands out as the central pillar of his legacy: the *Shōbōgenzō* (“Treasury of the True Dharma Eye”). This multi-fascicle collection of essays and sermons is widely regarded as his masterwork, exploring key Buddhist concepts through philosophical reflection, poetic expression, and engagement with kōans. Within this larger work, individual fascicles such as *Genjōkōan* (“Actualizing the Fundamental Point”), *Bendōwa* (“On the Endeavor of the Way”), *Uji* (“Being–Time”), *Sansuikyō* (“Mountains and Waters Sūtra”), *Busshō* (“Buddha-Nature”), *Zazenshin* (“Acupuncture Needle of Zazen”), and *Gyoji* (“Continuous Practice”) have become especially influential. Together they articulate a vision in which practice and realization are not two separate stages but a single, seamless reality.

Alongside the *Shōbōgenzō*, several other works illuminate different facets of Dōgen’s teaching and community life. The *Eihei Kōroku* (“Extensive Record of Eihei Dōgen”) gathers his formal sermons, informal talks, verses, and public addresses, offering a more immediate sense of his spoken style and interaction with disciples. The *Shōbōgenzō Zuimonki* (“Record of Things Heard”) presents informal talks and responses to questions, preserving the living voice of instruction as it was remembered by close students. These collections show Dōgen not only as a subtle philosopher but also as a practical teacher responding to concrete situations.

Dōgen’s emphasis on meditation and disciplined communal life appears with particular clarity in his shorter, more prescriptive writings. The *Fukanzazengi* or *Fukan Zazengi* (“Universal Recommendation of Zazen”) is a concise yet foundational guide to seated meditation, setting forth both instructions and rationale for zazen as the heart of the path. The *Eihei Shingi* (“Pure Standards for the Temple of Eternal Peace”) provides monastic regulations and guidelines for daily conduct, revealing how the vision of awakening is to be embodied in the rhythms of communal practice. The *Hōkyōki* (“Record of the Hōkyō Era”), which records Dōgen’s questions and exchanges with his Chinese teacher Tiantong Rujing, offers a glimpse into the formative dialogue that shaped his understanding.

Taken together, these writings disclose a teacher intent on unifying profound doctrine with the most ordinary details of practice. The philosophical depth of the *Shōbōgenzō*, the immediacy of the *Eihei Kōroku* and *Shōbōgenzō Zuimonki*, the meditative clarity of the *Fukanzazengi*, and the concrete standards of the *Eihei Shingi* all point toward a single thread: the realization of Buddha-nature in the very midst of everyday activity. Rather than separating study, meditation, and daily conduct, Dōgen’s corpus invites readers to see them as mutually illuminating dimensions of one continuous practice.
