Dongshan Liangjie

The Five Ranks attributed to Dongshan Liangjie set out five short verses pairing two terms Chan commentary translates roughly as the apparent, or conventional, and the real, or absolute: the apparent within the real, the real within the apparent, coming from within the real, arriving within both together, and unity attained. Read in sequence they trace a movement rather than a static classification, from ordinary perception, through recognizing the absolute nature underlying it, through the discovery that the absolute itself is only ever encountered inside ordinary particulars, and on to a state in which the distinction stops being useful at all. Later Caodong and, in Japan, Soto teachers used the scheme as a diagnostic tool for a student's stage of practice as much as a philosophical statement, checking which rank a given understanding still belonged to rather than treating enlightenment as a single undifferentiated event. The teaching is often read alongside the story of Dongshan's own awakening on seeing his reflection while crossing a stream, since both make the same point in different registers: what is sought is not separate from the ordinary image already in front of the practitioner, only unrecognized as such.

The Five Ranks are Dongshan Liangjie's best remembered teaching, but they were not a solitary production. Together with his own disciple, Caoshan Benji, Dongshan is credited as co-founder of the Caodong school of Chan, a name that combines a syllable from each of their associated mountains rather than naming either teacher alone, a detail article one's account of the Five Ranks themselves does not mention.

Dongshan was born in 807 in the Kuaiji region of what is now Zhejiang province, and died in 869. The school he and Caoshan built together outlived both of them by many centuries: transmitted to Japan, Caodong became the Soto school of Zen, which stands today as one of the two largest Zen lineages there alongside Rinzai, the school descended from Linji Yixuan.

A teacher and his own student sharing founder's credit, rather than a single named originator, is unusual among the Five Houses of Chan, most of which trace to one figure. That the Five Ranks became Caodong's philosophical signature rather than remaining one teacher's private formulation owes something to this shared founding itself: a system worked out and carried forward by two linked teachers, memorialized in a school name built from both of them, was better positioned to outlast either master than a teaching credited to one name alone.
