The lyrics evoke a sense of oneness with the sea. Becoming one with the shadow, the waves and the lull. The mention of the sky, clouds and dawn symbolize the passing of time and the arrival of something new.
The imagery of a white butterfly flinging itself into the sea further underscores the idea of surrender and merging with the ocean.
Overall, the song is a celebration of the beauty and power of the ocean, and the connection that exists between the self and the natural world. The use of traditional, deviant folk and world music elements contributes to the song's unique and haunting atmosphere.
