A list might tell us that Murugan is associated with a peacock, a Vel and a rooster banner. The lullaby does something more intimate with the same images. It addresses the deity affectionately, allowing the symbols to take their place within a relationship.
The surrounding verses bring further images of divine childhood and family. The reader can notice how large sacred themes are carried by a tender voice. That change of scale is part of the pleasure of reading a devotional collection across its different forms.
