The quote from "The Merchant of Venice" by William Shakespeare illustrates the theme of love and ownership in relationships. The speaker expresses a sense of unity and balance between two lovers, suggesting that their identities are intertwined. The repetition of "yours" emphasizes the deep emotional connection and the idea that one cannot wholly claim themselves when in love, as they give a part of themselves to their partner.

This declaration highlights the complexities of love, where personal boundaries blur, leading to an intimate bond that transcends individual ownership. It reflects the notion that in a true relationship, both partners share their hearts and souls, making them collectively responsible for each other’s well-being and happiness. Through this powerful expression of shared existence, Shakespeare captures the essence of love's transformative power.
