प्रदेशः — The Part for the Whole: Reference and Sampling

Pradeśa means "a place" or "a part", and as a tantrayukti it is the device of reference to another place or to a part. The three authorities give it three distinct senses. Kauṭilya defines it as "establishing by what is yet to be said", with a forward reference: "or by conciliation, gifts, dissension and force — as we shall explain under calamities." Suśruta defines it as "establishing the matter at hand by what has passed", with an inference from a surgeon's record: "as he extracted the foreign body of Devadatta, so he will extract that of Yajñadatta." Cakrapāṇi defines it as stating by a part what cannot, because of its extent, be stated in full, and cites Caraka's close to the chapter on food and drink: "this portion, mostly in use, has been stated." Read together with atideśa (TY-11), these definitions reveal a striking mirror: Kauṭilya's atideśa looks back and his pradeśa forward, while Suśruta's pradeśa looks back and his atideśa forward. This article sets out the mirror, proposes that the three senses share the root meaning of the word — another place, or a part of the whole — and answers three objections: that one of the two authorities must be wrong, that Kauṭilya's pradeśa is indistinguishable from anāgatāvekṣaṇa, and that Caraka's partial statement is the fault of incompleteness. It concludes that pradeśa covers what modern research calls forward reference, inference from track record, and sampling. Series: तन्त्रयुक्तिविमर्शः · Tantrayukti Studies, TY-2026/12.
