निर्देशः — Unfolding the Brief: from Aims to Method

Nirdeśa, "statement in detail", is the partner of uddeśa. Kauṭilya defines it as an expanded sentence (vyāsa-vākya), and his example unfolds the very term his uddeśa had stated: conquest of the senses is "the non-transgression of the senses — ear, skin, eye, tongue and nose — in sound, touch, form, taste and smell." Suśruta defines it as expanded speech and unfolds his one-word uddeśa, śalya, into its two kinds, bodily and adventitious. Cakrapāṇi defines it as "the explanation of what was stated as enumerable", and points to the long passage of Caraka's first chapter in which cause, sign and remedy are opened out. This article shows that the three examples display the three ways a brief statement can be unfolded — by definition, by division and by exposition — and relates them to Vātsyāyana's "division of what was enumerated" and to the Nyāya lakṣaṇa. Three objections are answered: that nirdeśa is the same as vyākhyāna (exposition), that it is mere repetition of the uddeśa, and that Kauṭilya's example is a definition and therefore belongs to Nyāya rather than to tantrayukti. It concludes that nirdeśa is the discipline of keeping a promise exactly — unfolding what was compressed, no less and no more — and that its modern forms are the operational definition, the methods section and the hierarchical outline.
