It is understood from the pure-hearted that love is inherently the very subject of purity and chastity.

In this couplet, the poet reflects on a truth learned from those with pure hearts: genuine love is not a reckless passion, but the very essence of spiritual purity. It gently nudges us away from shallow desires, presenting love as an art of sacred integrity and selfless devotion. To truly love someone, the verse reminds us, is to cleanse one's own soul first.
