It is good that my heart became trapped in the beloved's tresses, for it had set out to drown and die in the well of her dimpled chin.

Here, the poet uses a delightfully playful conceit of classical Urdu poetry. The heart was on a reckless mission, heading straight to drown in the deep 'well' of the beloved’s chin dimple—a classic metaphor for fatal attraction. Fortunately, along the way, it got caught and entangled in her long, dark tresses instead. The lover wryly celebrates this captivity, glad that being trapped in her locks saved him from drowning completely!
