因明入正理論疏 1.15

1.15

商羯羅主菩薩造者，梵云商羯羅塞縛彌菩提薩埵訖栗底。商羯羅者，此云骨瑣。塞縛彌者，此云主。菩提薩埵，義如常釋。訖栗底者，造。唐音應云：骨瑣主菩薩造。外道有言：成劫之始，大自在天人間化導，二十四相，匡利既畢，自在歸天。事者顧戀，遂立其像，像其苦行，悴疲飢羸，骨節相連，形狀如瑣，故標此像名骨瑣天。劫初雖有千名，時減猶存十號，此骨瑣天即一名也。菩薩之親，少無子息，因從像乞，便誕異靈，用天為尊，因自立號，以天為主名骨瑣主，即有財釋。此論是彼之所造也。

Regarding "composed by the Bodhisattva Śaṅkarasvāmin": In Sanskrit, Śaṅkarasvāmin-bodhisattva-kṛti. "Śaṅkara" is translated here as "bone-chain" [i.e., Śaṅkara / skeleton-chain]. "Svāmin" is translated here as "master" [svāmin]. "Bodhisattva" has its meaning explained as usual. "Kṛti" means "composed". In the language of Tang, it should be said: "composed by the Bone-Chain Master Bodhisattva". The non-Buddhists say: At the beginning of the kalpa of formation, Maheśvara transformed and guided humanity with twenty-four marks; having completed his work of aiding and benefiting, the Sovereign returned to heaven. His worshippers longed for him with affectionate attachment and thereupon erected his image, depicting his ascetic practices—exhausted, weary, starved and emaciated, with joints interconnected like a chain, his form resembling a chain—and therefore designated this image the "Bone-Chain Deva". Although at the beginning of the kalpa he had a thousand names, as the era declined ten titles still remained, and this Bone-Chain Deva was one of those names. The parents of the Bodhisattva had no sons in their youth; having prayed before this image, they gave birth to this extraordinary spirit. Taking the deva as supreme, they thereupon established his name after him; taking the deva as lord, he was named "Bone-Chain Master" (Śaṅkarasvāmin)—which is an exocentric compound (bahuvrīhi). This treatise is what was composed by him.
