Here are a couple of examples of Bill Staines lyrics that strike me as especially poetic.

From "Secret Garden":

Grasping at love is like holding a fistful of sand

The harder you squeeze, the less that you have in your hand

And the refrain from "Crossing the Water"

We are crossing the water our whole lives through
Making a passage that is straight and true

Every heart is a vessel, every dream is a light

Shining in the darkness of the blackest night
