There are those who stare East with eyes widened...waiting for the Sun to rise so that they may come to life. They see the light falling on every object, animate and inanimate, as it changes in the light of the burning sun. They see the light, with their own two eyes.
Then there are those, who close their eyes and then 'feel' the sun rise beneath the eyelids. They observe the world with every sense, as their covered vision changes color from black to golden-red. Even they know that the sun is high...but they haven't even opened their eyes yet.
