Sāṅkhya of Creation and Annihilation
Sarga–Nirodha-viveka
यस्तु यस्यादिरन्तश्च स वै मध्यं च तस्य सन् । विकारो व्यवहारार्थो यथा तैजसपार्थिवाः ॥ १७ ॥
yas tu yasyādir antaś ca sa vai madhyaṁ ca tasya san vikāro vyavahārārtho yathā taijasa-pārthivāḥ
あるものの始めと終わりである原因素材は、その中間にも同じく在る。変化とは、便宜のために与えられた名と形にすぎない。金から腕輪や耳飾りが作られ、土から壺や小皿が作られるが、始めにも終わりにも金と土が残るゆえ、現れの期間にもそれらが基盤として存在し、形の現実性を支えている。
The Lord here explains that the original cause is certainly present in its effect, citing the example of gold and clay functioning as the causal ingredients of many different products in which gold and clay continue to be present. For our convenience, we assign different names to temporary products, although their essential nature continues to be that of the ingredient, and not of the temporary product.
It says that change is described for practical convention, while the underlying substance that appears as beginning, middle, and end remains the same.
To give Uddhava steady discrimination: seeing that material forms arise and dissolve, while the underlying cause/substance persists, one becomes detached and fixed in spiritual understanding.
Treat shifting circumstances—success, loss, praise, blame—as temporary ‘forms’ and focus on the enduring spiritual goal: devotion and inner steadiness rather than anxiety over changing externals.
