Just as erroneous vision produces two moons, so exists Brahman, oh Bhārata. Even looking, I do not see; I am confused by the illusion in the heart.

The analogy of the double moon—dvicandra—constitutes a classic motif within Indian epistemology. The afflicted eye perceives two moons where only one exists. The second moon does not exist in some intermediary state; it is a pure appearance devoid of ontological substratum. Such is the case with the phenomenal world vis-à-vis Brahman. Māyā does not engender a second real domain, but rather superimposes an appearance upon the singular existent. The existential implication is immediate: whenever we attribute intrinsic reality to our mundane preoccupations, we are perceiving a double moon. The imperative—not ethical but gnoseological—is to restore the organ of perception so that it may apprehend without duplication. The Yoga Sūtra of Patañjali designates this as viveka, the discriminative faculty that disentangles the real from the apparent. This constitutes no mere philosophical abstraction, but rather a perceptual correction analogous to adjusting the lens of an optical instrument.
