In plain words
Just as the sun brings forms to light and the eye perceives them clearly, while in darkness nothing is revealed; in the exact same way, just as the sun presides over the eye, so the supreme master who presides even over the sun is none other than my own innermost Self—this is the true relationship. He is the master of all egoistic states of mind. The scriptures speak of the sun as inspiring the intellect only in the sense that the sun activates the physical eye, which in turn awakens mental clarity; or rather, the text points directly to the nature of the ultimate ruling Self, as the verse declares: 'The sun is the Self of all that moves and stands.' If someone asks whether the Self itself needs yet another light to illuminate it, the answer is no—because the Self is inherently self-luminous, and scripture explicitly rules out any other seer apart from it.
Close to the Sanskrit
Just as the sun illumines the visible form and the eye grasps it distinctly, whereas in darkness nothing is seen; similarly, just as the sun is a single overseer of the eye, so the supreme overseer of even the sun is myself as the Self—this is the relationship. He is also the controller of ego-notions. Through scripture, intending the sun's capacity to preside over the eye, the sun's power to inspire the intellect has been stated, because the eye energized by the sun produces mental activity; or else this is spoken intending the nature of the ruling Self, as declared: 'The sun is the Self of all that moves and stands.' If an objection is raised that the Self too must be presided over by another light, we reply no, because of its self-luminous nature, and because scripture prohibits any other seer apart from it.
