And what is the appearance of that person? Like a saffron-coloured raiment, like white wool, like cochineal, like the flame of fire, like the white lotus, like sudden lightning. He who knows this, his glory is like unto sudden lightning. Next follows the teaching (of Brahman) by No, no! for there is nothing else higher than this (if one says): 'It is not so.' Then comes the name 'the True of the True,' the senses being the True, and he (the Brahman) the True of them.

In plain words: That inner person is described with bright images: saffron cloth, white wool, red dye, a flame, a white lotus, a flash of lightning. Whoever knows this shines like lightning. But Brahman, the ultimate reality, is best described as "not this, not this," because nothing we can name captures it. It is called "the Truth of the truth." Our senses are true, and Brahman is what makes them true.
