Śivasaṃhitā 1.49

A relentless critique of knowledge systems built on false premises. The Śivasaṃhitā calls kalpaka (builder, imaginer) one who speculates about reality without having touched its direct foundation. The knowledge produced by such speculation—however refined—is mithyā (false): not a partial error but a root distortion.

The term kalpita (imagined, constructed, hypothetical) contrasts with aparokṣa (direct, unmediated knowledge). The vidyā of the kalpaka is conceptually elaborated knowledge, not realization. Mṛṣātmikā (whose essence is false) indicates that this is not a correctable error with more information: it is a constitutive error that requires an epistemological change of level.

This critique has a precise target in the text’s context: to discredit philosophers who, without practice or direct realization, construct systems about ātman and brahman. The Śivasaṃhitā, as a yoga text, privileges direct experience over theoretical elaboration. True knowledge (aparokṣa jñāna) only arises from sustained practice and the grace of the guru.
