from Q&A with KnA“That knowledge by which one sees the one imperishable Being in all beings, undivided in the divided, is sattvic (18.20). That which sees only the manifold, distinct existences in the various beings, is rajasic (18.21). And that which clings, irrationally and without grasp of truth, to a single effect as though it were the whole, is tamasic (18.22).” As you rightly note: oneness-in-diversity is the sattvic knowing (the vision of 13.16, 13.27); distinction-only — seeing the many and missing the One — is rajasic; and not using the intellect at all, latching onto one narrow thing as if it were everything, is tamasic. This is the Gītā’s epistemology in miniature: the quality of one’s seeing is itself graded by the guṇas, and only the sattvic sight sees the unity that liberates.
