"The measure" [lyric]

The measure of a day remains familiar
    the measure of a life remains obscure
            I set out in the morning
            with promises a'bourning
    by eventide I barely could endure!

The measure of a line remains familiar
    the measure of a life remains opaque
            I had no map but travelled
            the land itself unravelled
    the gentle heart were oft' inclined to break!

The measure in a song became familiar
    the measure in a life I ne'er could grasp
            the ocean drowned all castles
            the games became mere hassles
    the shore looked barren yet the sea was vast!
