This is the quote I have selected. It's from The Medusa Frequency:
"Fidelity is a matter of perception; nobody is unfaithful to the sea or to the mountains or to death; once recognized they fill the heart. . . Anyone who loves, anyone who perceives the other person fully can only be faithful, can never be unfaithful to the sea and the mountains and the death in that person, so pitiful and heroic is it to be a human being."
