Sandokai: Harmony of Difference and Sameness Ts'an-t'ung-ch'i, By Ch'an Master Shih-t'ou Hsi-ch'ien
Harmony is movement as presented by Master Shih-t'ou while the writing is visual and our thinking harmonic as well. Seeing the interplay and thinking rhythm of the mind thoughts represent the non static nature of the Dharma. Even nothing is not standing still, just as nothing is impermanent.
The ebb and sway of form, excited by subatomic stuff, suggest "a tube containing mirrors and pieces of colored glass or paper, whose reflections produce changing patterns that are visible through an eyehole when the tube is rotated." https://us.search.yahoo.com/yhs/search?hspart=ima&hsimp=yhs-001&p=colidiscopic&type=q3060_A2FPL_sep_bcrq
Hojo Michael Elliston has a musical adaptation of the Sandokai and among other sutra's and teachings. This engulps the momentum of Buddha nature as offered by Master Shih-t'ou. When you read the work below, hum it, sing it, taste it, smell it, think it, sway with it, snap your fingers to it, become immersed, swim in it and smile:
Harmony of Difference and Sameness
竺土大仙心 The mind of the great sage of India
東西密相付 is intimately transmitted from west to east.
人根有利鈍 While human faculties are sharp or dull,
道無南北祖 the Way has no northern or southern ancestors.
靈源明皎潔 The spiritual source shines clear in the light;
枝派暗流注 the branching streams flow on in the dark.
執事元是迷 Grasping at things is surely delusion;
契理亦非悟 according with sameness is still not enlightenment.
門門一切境 All the objects of the senses
迴互不迴互 interact and yet do not.
迴而更相涉 Interacting brings involvement.
不爾依位住 Otherwise, each keeps its place.
色本殊質像 Sights vary in quality and form,
聲元異樂苦 sounds differ as pleasing or harsh.
闇合上中言 Refined and common speech come together in the dark,
明明清濁句 clear and murky phrases are distinguished in the light.
四大性自復 The four elements return to their natures
如子得其母 just as a child turns to its mother;
火熱風動搖 Fire heats, wind moves,
水濕地堅固 water wets, earth is solid.
眼色耳音聲 Eye and sights, ear and sounds,
鼻香舌鹹醋 nose and smells, tongue and tastes;
然於一一法 Thus with each and every thing,
依根葉分布 depending on these roots, the leaves spread forth.
本未須歸宗 Trunk and branches share the essence;
尊卑用其語 revered and common, each has its speech.
當明中有暗 In the light there is darkness,
勿以暗相遇 but don't take it as darkness;
當暗中有明 In the dark there is light,
