Śivasaṃhitā 2.46

Two analogies are juxtaposed: the cyclical birth of beings to exhaust their karma (bhoga) and the classic epistemological example of an oyster shell mistaken for silver. Both illustrate the same mechanism — a perceptual defect (doṣa) superimposes a false appearance onto a real substrate. The phenomenal world becomes, in this reading, an āropaṇa (superimposition) projected onto underlying Brahman.

Āropaṇa (superimposition, erroneous attribution) is a central technical term in Advaita epistemology, prominent in Śaṅkara’s Adhyāsabhāṣya. Doṣa (defect, impurity, error) here designates the perceptual flaw generating confusion. Śukti (oyster shell) and rajata (silver) form the classic śuktikā-rajata pair, the Indian equivalent of the rope-snake illusion.

The shell-silver metaphor is among the most recurrent in Advaita literature for explaining adhyāsa. Its presence in the Śivasaṃhitā reveals Vedāntic philosophical influence on medieval tantric-yogic texts, demonstrating that yoga practice cannot be separated from a correct understanding of the nature of reality.
