The Five Ranks, by Chinese Soto (Caodong) master Tung-shan, are fundamental to Sōtō and Rinzai Zen teaching, expressing the interplay of absolute and relative truth and the fundamental non-dualism of Buddhist teaching.

The ranks are based on a translation of five stanzas from a poem attributed to Tung-shan, who may have received it from his master before him:
When Buddhism was intriduced in China the doctrines of Buddha-nature and Sunyata were being understood as akin to Tao. It took the Chinese world several centuries to realize that sunyata has another meaning[1]. The Prajnaparamita-sutras and Madhyamaka emphasized the non-duality of form and emptiness: form is emptiness, emptiness is form, as the heart sutra says.[2] The idea that the ultimate reality is present in the daily world of relative reality fitted into the Chinese culture which emphasized the mundane world and society. But this does not tell how the absolute is present in the relative world:
To deny the the duality of samsara and nirvana, as the Perfection of Wisdom does, or to demonstrate logically the error of dichotomizing conceptualization, as Nagarjuna does, is not to address the question of the relationship between samsara and nirvana -or, in more philosophical terms, between phenomenal and ultimate reality [...] What, then, is the relationship between these two realms?[3]
This question is answered in such schemata as the Five Ranks of Tozan[4] and the Oxherding Pictures.
