The couplet suggests that the soft sighs and emotional expressions from the heart, which were once characteristic, are no longer present. The atmosphere or mood of love has changed or deteriorated.

This beautiful couplet speaks to the fragility of deep emotion. The poet describes a time when the sigh of love (आह) came effortlessly, naturally flowing from the heart. But now, the very atmosphere of love—the 'climate of affection'—has changed. It suggests that the initial purity and ease of passion have been corrupted or complicated by time and external circumstances. It is a lament for lost simplicity in love.
