Śivasaṃhitā 1.21

This verse dissects the karmakāṇḍa into its fundamental normative polarity: vidhi (injunction, positive command) and niṣedha (prohibition, negative restriction). The entire edifice of Vedic ritual ethics rests on this binary. The second half of the verse delivers the moral consequence directly: performing a prohibited act inevitably produces pāpa — karmic defilement — the adverb niścitam («certainly») leaving no ambiguity.

Vidhi derives from vi-dhā (to ordain, arrange), designating positive prescription; niṣedha from ni-ṣidh (to repel, restrain), the negative counterpart. Pāpa should not be conflated with Western theological «sin»: it is a karmic residue that clouds consciousness and impedes spiritual progress. The certainty embedded in niścitam reflects the inexorable logic of karmic causation.

This taxonomy is rooted in Mīmāṃsā philosophy, where vidhi and niṣedha are central hermeneutical categories for interpreting Vedic injunctions. By engaging this framework, the Śivasaṃhitā demonstrates mastery of classical Brahmanical thought before moving beyond it. Ethical conduct governed by these categories is not rejected by yoga but absorbed as its necessary foundation.
