Final answer:
The lines from Tennyson's poem express the theme of individuality and destiny, using the metaphor of worms spinning their cocoons to symbolize how each person shapes their own life and future.
Step-by-step explanation:
The lines from Tennyson's poem 'Two voices' encapsulate the theme of individuality and destiny. Tennyson uses the metaphor of worms spinning their cocoons to illustrate how every individual follows a unique path and faces different experiences in life. Each of us toils in our own way, influenced by different circumstances, thus spinning our own 'cocoon.'
The cocoon, in this context, symbolizes a personal destiny or life's work shaped by individual efforts and challenges. Just as worms spin cocoons unique to themselves, humans forge their paths, highlighting the diversity of individual experiences within the human condition.
