It is the light of lights, the light even of the sun and the rest; for the lights, the sun and the rest, kindled by the light of the Self's consciousness, shine, by such scriptures as 'kindled by His radiance the sun gives heat; by His shining all this shines' (Śvetāśvatara 6.14), and by the remembered text here itself, 'the radiance that is in the sun' and the rest. It is said to be beyond the darkness, beyond ignorance, untouched by it. To hold up one who has fallen into despondency, thinking knowledge and the rest hard to come by, He says: knowledge, humility and the rest; the thing to be known, that which was told by 'the thing to be known, which I shall declare' (Gītā 13.12) and the rest; and the goal of knowledge, the very thing to be known which, once known, is the fruit of knowledge, and so is called the goal of knowledge, while as still being known it is the thing to be known. These three are particularly set, established, in the heart, the intellect, of every living being; for it is there alone that the three are made evident. This verse is begun to round off the matter as told.
