Your lost friends are not dead, but gone before, advanced a stage or two upon that road which you must travel in the steps they trod.
— Aristophanes

Faith is that strengthening power within Urging me on my way, Teaching me all that I must know, Helping to obey. Faith is that strengthening power within Lighting the road I trod, Helping me know which way to go, Pointing the way to God.
Unknown trod quote

Come on, insisted Zaphod, I've found a way in.In? said Arthur in horror.Into the interior of the planet! An underground passage. The force of the whale's impact cracked it open, and that's where we have to go. Where no man has trod these five million years, into the very depths of time itself ...Marvin started his ironical humming again.Zaphod hit him and he shut up.With little shudders of disgust they all followed Zaphod down the incline into the crater, trying very hard not to look at its unfortunate creator.Life, said Marvin dolefully, loathe it or ignore it, you can't like it.
— Douglas Adams

Oh! I have slipped the surly bonds of earth, and danced the skies on laughter-silvered wings and while with silent lifting mind I've trod the high, untrespassed sanctity of space, put out my hand and touched the face of God.
— John Gillispie Magee, Jr.

The feet of the humblest may walk in the field Where the feet of the Holiest trod, This, then, is the marvel to mortals revealed.
— trod quotation by Phillips Brooks
