Overview
Although the Vaisheshika system developed independently from the Nyaya, the two eventually merged because of their closely related metaphysical theories. In its classical form, however, the Vaishesika school differed from the Nyaya in one crucial respect: where Nyaya accepted four sources of valid knowledge, the Vaishesika accepted only perception and inference. Although not among Kanada's original philosophies, later Vaishesika atomism also differs from the atomic theory of modern science by claiming the functioning of atoms(or their characterization because of which they function in their way) was guided or directed by the will of the Supreme Being or Supreme Concept.
An alternative view would qualify the above in that the holism evident in the ancient texts mandate the identification of six separate traditional environments of philosophy, consisting of three sets of two pairs.
