This verse presents another powerful analogy — the sun and the soul. Just as a single sun illuminates the entire solar system, a single soul illuminates the entire body with consciousness. The analogy is precise and instructive on multiple levels.

First, the sun is one but its light reaches everywhere within its sphere. Similarly, the soul is one within each body, but its consciousness reaches every part — from the tip of the toe to the crown of the head. When the soul is present, the entire body is conscious and responsive. When the soul departs, the body becomes inert matter, just as a region plunged into darkness when the sun sets.

Second, the sun illuminates without being affected by what it illuminates. Sunlight falls equally on clean and dirty surfaces, on palaces and gutters. The sun is never contaminated by what it shines upon. Similarly, the soul illuminates the body with consciousness regardless of the body’s condition — healthy or diseased, young or old, in pleasure or pain — without itself being contaminated.

Third, the analogy reinforces the distinction between the field (kshetra) and the knower of the field (kshetree). The body is the field — it is the object of illumination. The soul is the knower — it is the source of illumination. Without the soul, the body has no awareness, no experience, no life. Consciousness is not a product of the body; it is the gift of the soul to the body.

This understanding has an important implication: consciousness is evidence of the soul. Wherever there is awareness — in a human, an animal, an insect — there is a soul. The soul’s presence is proven by its symptom: consciousness, just as the sun’s presence is proven by light.
