This sonnet was first published in 1609. Its structure and form are a typical example of the Shakespearean sonnet (3 quartrains + 1 couplet) = 14 lines. 

This Sonnet talks about how the forge of true minds and love can stand the test of time despite any hurdle it may face in between; it stands as one of my favourite Shakespearean Sonnets. May you feel a sense of strength and hope towards love and life after listening to this verse!
