This is the reward received for enduring the pain of separation; now let anyone dare follow the bidding of their heart.

There is a sharp, bitter irony here in the word 'daad', which usually means praise or a fitting reward. The speaker followed their heart blindly into love, only to receive the agony of separation as their prize. It sounds like an exhausted lover laughing through their tears, warning anyone listening never to make the mistake of trusting their foolish heart again.
