Within the broad ocean of the Shōbōgenzō, certain fascicles have come to be regarded as especially luminous because they gather Dōgen’s vision of practice and realization into a few concentrated teachings. Genjōkōan, often treated as his most representative essay, speaks of “actualizing the fundamental point” and presents the heart of Zen as the living kōan of this very life. Here Dōgen articulates that to study the Way is to study the self, to forget the self, and to be confirmed by all things, dissolving the imagined gap between delusion and enlightenment. Rather than treating awakening as a distant attainment, this fascicle shows how each moment of sincere practice is already the full manifestation of the Buddha Way.

Uji, “Being–Time,” is renowned for its profound reworking of how existence and temporality are understood. In this text, time is not a neutral backdrop or a mere sequence of instants, but is inseparable from being itself: each being is a time, and each moment is complete. This vision undergirds the Sōtō emphasis on “just this moment,” suggesting that every instant of practice is the total expression of Buddha-nature. The fascicle’s philosophical depth has made it a touchstone for those who seek to contemplate how every fleeting experience is, in fact, the full presence of the Way.

Other fascicles gain their prominence by clarifying how this vision is embodied in concrete practice. Bendōwa, “On the Endeavor of the Way,” functions as a kind of manifesto, defending and explaining zazen as the very heart of the path and treating meditation not as a means to an end but as practice-realization itself. Zazengi and related instructions on seated meditation further specify how body and mind are to be engaged, so that posture, breath, and awareness become the Buddha’s own activity rather than techniques for acquiring a special state. In this light, the rules and forms of practice are not mere external discipline but the living shape of awakening.

Fascicles such as Busshō, “Buddha-Nature,” and others that explore the unity of body and mind extend this same insight into doctrinal and existential reflection. Buddha-nature is not presented as a hidden essence waiting to be uncovered, but as the immediate, dynamic functioning of all beings, animate and inanimate, when seen through the eye of practice. Together, these writings articulate the core Sōtō themes of non-duality, the universality of awakening, and the dignity of ordinary activities. Their enduring significance lies in how they invite practitioners to recognize that this very body-mind, in this very moment, is already the complete expression of the Dharma.
