Shakespeare's Sonnet 116 argues that true love is constant and does not change over time or due to external challenges. In the first two lines, Shakespeare states that true love should not be impeded by obstacles and that if love can change or be removed, it is not real love. The rest of the first 12 lines then provide examples of how true love remains steadfast: it is an ever-fixed point unaffected by storms; it guides one's journey in life though its worth cannot be measured; and it continues looking out for one's well-being even from a distance. The sonnet presents Shakespeare's view that true love transcends physical or temporal changes to remain eternal.
