The 'yes, yes' trade refers to an exchange of empty or insincere words. Despite this superficiality, my innermost being is completely dedicated to you.

This couplet speaks to the difference between outward politeness and deep inner truth. It suggests that while the world often engages in a 'trade of yes-yes words' – superficial pleasantries or flattery – our truest, innermost self is profoundly shaped and defined by a significant 'you'. It beautifully contrasts the external show of respectful words with the deep, genuine impact of a cherished person or presence on our very being, emphasizing that our core essence is because of them.
