Explanation:

William Shakespeare's (1564-1616) Sonnet 116 is about love. In the start, the poet uses negation by pointing out what love is NOT. According to him love is not that changes with circumstances. In line number 5 he says that love remains the same, like a fixed mark. It is steadfast (O no! it is an ever-fixed mark). In line number 6, he says that love looks on tempests (hard times), and remains the same, meaning hard times can not alter love (That looks on tempests and is never shaken;)

In line number 7, Shakespeare says love is like a star or lighthouse which guides wandering human beings (It is the star to every wand'ring bark). So, metaphor in line 7 of Shakespeare"s Sonnet CXVI is "Love is compared to the guiding star for all earthly travelers."

Shakespeare's Sonnet 116 is;

Let me not to the marriage of true minds

Admit impediments. Love is not love

Which alters when it alteration finds,

Or bends with the remover to remove.

O no! it is an ever-fixed mark

That looks on tempests and is never shaken;

It is the star to every wand'ring bark,

Whose worth's unknown, although his height be taken.

Love's not Time's fool, though rosy lips and cheeks

Within his bending sickle's compass come;

Love alters not with his brief hours and weeks,

But bears it out even to the edge of doom.

If this be error and upon me prov'd,

I never writ, nor no man ever lov'd.
