Shikantaza Talks

Shikantaza (只管打坐) is Dogen's Japanese translation of the Chinese phrase zhǐguǎn dǎzuò (只管打坐 / 祇管 打坐), "just sitting." The phrase was used by his teacher Rujing, a monk of the Caodong school of Chan Buddhism, to refer to the meditation-practice called "Silent Illumination" (Chinese: 默照禅), or "Serene Reflection," taught by the Caodong master Hongzhi Zhengjue (1091–1157). In Japan, it is associated with the Zen Soto school. In shikantaza one does not focus attention on a specific object (such as the breath); instead, practitioners "just sit" in a state of conscious awareness.
