M4:52 — چون درآمد خوش در آن باغ آن جوان / خود فرو شد پا به گنجش ناگهان

This couplet marks the turning point in the story, shifting from the general principle of spiritual struggle to a specific, dramatic moment of grace. The young lover, fleeing the night watchman (ʿasas), has just entered a random garden to hide. The word khosh (خوش), meaning 'happily' or 'delightedly', is ironic; he is happy merely to have escaped, unaware of the greater joy awaiting him.

The second line, "his foot sank suddenly, straight into its treasure," is a classic Persian literary trope. Finding a buried treasure (ganj, گنج) symbolizes the discovery of something of immense, unexpected value. Here, the 'treasure' is his beloved, whom he finds in the garden. Rumi uses this physical, almost cinematic image to represent a profound spiritual truth: the moment of divine grace often arrives suddenly, in the midst of trouble, and through the very circumstances we perceive as disastrous. The fear of the watchman, a seeming misfortune, becomes the direct cause of his union with the beloved.
