Samadhi (Jp.: zanmai
) is a term used often in Zen. It is used several ways:
Samadhi can refer to a state of meditative absorption in which dualistic habit and fixation is lessened.
Samadhi can refer to specific states that are expressions of deepening and integrating the recognition of one's nature, which are meticulously examined and cultivated within the course of Zen training. For example the Jewel Mirror Samadhi (hokkyo zanmai
) and the alternate samadhis of hen and sho ([i]hen sho ego zanmai
Samadhi can refer to the fruition of Zen, which is Zenjo (Skt: Dhyana-samadhi
) in which the recognition of kensho
is the perfection of vipashyana
, and the continual arising of that recognition in the midst of activity is the perfection of shamatha
. These in union are Zenjo. It could also be described as the union of wisdom and means, essence and function, emptiness and compassion, Manjusri and Samantabhadra, actualization of the 4 wisdoms/3 bodies, etc.
Non-thinking or no-thought (munen
) refers to a mind which functions freely without stopping or fixating. This is also called no-mind (mushin
Non-meditation is the encompassing of all activity of body, speech and mind within meditation. That is, one is never not practicing.
What I wrote above reflects Rinzai common usage of these terms. Other traditions may have different or additional usages. What was your question?
