Note 7 — Chapter I · THE CHÁRVÁKA SYSTEM.
Edward B. (Edward Byles) Cowell translation
Kiṇwa is explained as "drug or seed used to produce fermentation in the manufacture of spirits from sugar, bassia, &c." Colebrooke quotes from Śaṅkara: "The faculty of thought results from a modification of the aggregate elements in like manner as sugar with a ferment and other ingredients becomes an inebriating liquor; and as betel, areca, lime, and extract of catechu chewed together have an exhilarating property not found in those substances severally."
