Cover art for Crystal Days lyrics by Echo and the Bunnymen

The pleasure of pain endured To purify our misfit ways And magnify our crystal days

This is a beautiful 3 lines taken out of a beautiful verse taken out of a great song. He's saying that he has been waiting and enduring the pain which is really his pleasure because it will only serve to magnify the crystal days these two people have ahead of them. It's about a purifying love.
