The heart's tale flows out through the eyes, which is a mistake, even though the lips' petals are closed.

This couplet beautifully conveys how our eyes often betray our true feelings, even when we try to keep them hidden. It says that the secrets of our heart flow out through our eyes, almost like a mistake by the eyes themselves, even when our lips are sealed. This means that no matter how much we try to conceal our emotions or thoughts by remaining silent, our eyes become the windows to our soul, inadvertently revealing what's truly within us. It's a poignant observation on human expression, highlighting the powerful, unspoken language of the eyes.
