Who wrote the line, "Let me not to the marriage of true minds admit impediments."?

The line, "Let me not to the marriage of true minds admit impediments." is found in the 'Sonnet 116' by William Shakespeare. Although Shakespeare usually refers to romantic love in his sonnets, here critics have interpreted this sonnet as a deep love for a friend or family member. The idea of someone having a true and strong love for a friend (relative) is keenly explored in Shakespeare's 'Sonnet 116.'

A key and central theme in 'Sonnet 116' is that love as a constant force that cannot waver even during a very long period of time. This poem is said to stress the idea that love is indispensable; it challenges the idea that love will ever wane over time. The words here tell us that the essence of love and friendship for the poet are apparently based on reciprocity or mutuality.

In 'Sonnet 116,' the ideal relationship is referred to as "the marriage of true minds," a perfect union that is clearly realized when dedicated and faithful individuals come together.
