For entering more deeply into shikantaza, it is helpful to draw on both classical Soto Zen sources and modern expositions that clarify their intent. Among the traditional texts, Dōgen’s *Fukanzazengi* (“Universal Recommendation of Zazen”), *Bendōwa* (“Wholehearted Way”), and selected fascicles of the *Shōbōgenzō* such as “Genjōkōan” are especially central, as they articulate zazen as the very heart of the path rather than a technique aimed at a later result. Keizan’s *Zazen Yōjinki* (“Notes on What to Be Aware of in Zazen”) further refines this by offering concrete guidance on posture, attitude, and common pitfalls. Together, these writings sketch a vision of “just sitting” in which practice and realization are not two separate stages but a single, seamless activity.

Modern teachers have labored to express this vision in language accessible to contemporary practitioners. Shunryu Suzuki’s *Zen Mind, Beginner’s Mind* is often regarded as foundational in conveying the attitude of shikantaza, emphasizing a fresh, ungrasping mind rather than technical achievement. Kōshō Uchiyama’s *Opening the Hand of Thought* is widely valued for its detailed, practical instructions on posture and the handling of thoughts, and his further writings continue this exploration. Shohaku Okumura’s works, including his commentary on “Genjōkōan,” deepen the philosophical and existential dimensions of Dōgen’s teaching while remaining rooted in the simplicity of just sitting. These authors, though varied in style, consistently point back to the same essential orientation: sitting upright, allowing thoughts to come and go without interference, and trusting zazen itself as the full expression of the way.

Beyond books, living communities and teachers provide an indispensable context for this subtle practice. Soto Zen temples and centers, including those associated with San Francisco Zen Center, Antaiji, and other traditional monasteries, commonly offer introductory instruction in zazen and opportunities to sit with experienced practitioners. Online communities such as Treeleaf Zendo make teachings and guided sittings available to those who cannot easily reach a temple, while many Soto centers publish written instructions and recorded talks that focus specifically on shikantaza. Recordings of talks by teachers such as Shunryu Suzuki, Kōshō Uchiyama, and Shohaku Okumura can serve as a steady accompaniment, clarifying how the spirit of just sitting permeates daily life as well as formal meditation.

When engaging these resources, it is helpful to discern whether they present shikantaza in a way that resonates with this core Soto understanding. Reliable teachings describe zazen as sitting with no special object, mantra, or visualization, simply allowing experience to unfold without suppression or indulgence. They emphasize that this practice is not a means to an end but the direct enactment of awakening itself, however ordinary it may appear. Approached in this way, the recommended texts, centers, and teachers do more than convey information; they invite a reorientation of the whole life around the quiet, unadorned act of just sitting.
