"What if one were to run after a ray of light?"

Enough, she thought, seeing the first ray of light, that he might give way to compassion?

And then, with the last rays of light, he did.

His conduct was the one single ray of light in an otherwise dark day.

As he did so a ray of light fell upon his face.

He saw another ray of light and reached for the phone.

Not a ray of light is cast on the music.

And then came a ray of light into my darkness: there was you.

With the very first rays of light it came alive in me: hope.
