Here are some examples of how Shakespeare unlocks his heart in the sonnets:
* In Sonnet 18, he compares his love to a summer day, and he says that it is "more lovely and more temperate." He also says that his love will "never fade."
* In Sonnet 29, he writes about how his love for his friend has made him a better person. He says that his friend has "taught me to see, and to hear, and to think."
* In Sonnet 55, he writes about how his love for his friend is stronger than death. He says that their love will "survive when beauty doth cease."
* In Sonnet 116, he defines what love is. He says that love is "an ever-fixed mark, / That looks on tempests and is never shaken."
These are just a few examples of how Shakespeare unlocks his heart in the sonnets. The sonnets are a powerful and moving work of art that offer a glimpse into the soul of one of the greatest writers of all time.
