'Our light is harder-
unafraid to brandish its teeth.'
This shows cause and effect, the connotations of wild; the opposite of tame; to be uncontrolled is certainly evident within this stanza. Subsequently the last line of the poem reads 'there are things we cannot hide'; this then points to the change in the line break during the fourth stanza and also reveals the reason why. The light 'Paints everything as it is' and under its gaze lays bare those things once hidden, this is what is beautiful.
