Note 216 — Chapter XI · THE AKSHAPÁDA (OR NYÁYA) DARŚANA.

This refers to the couplet so often quoted in Hindu authors, "Logic, the three Vedas, trade and agriculture, and the eternal doctrine of polity,—these four sciences are the causes of the stability of the world" (cf. Manu, vii. 43). It occurs in Kámandaki's Nítisára, ii. 2, and seems to be referred to in Vátsyáyana's Com. p. 3, from which Mádhava is here borrowing.
