From the poem "wild nights" by emily dickinson, what do the compass and the chart symbolize?

The compass and the chart symbolize reason, temperance, caution. She doesn't need them anymore, as her heart is in port, and the winds can do it no harm now. The poem is about passionate love which is not yet realized. The meaning of those symbols in the second stanza is that if she were to unite with her lover, her heart would need no guidance from reason anymore, as she needs it now.

No longer does a lover require compass or chart on troubled seas, since in finding love, the voyage is done, the "port" reached. It symbolizes that these are now meaningless.
