M3:4389 — موج می‌زد در دلش عفو گنه / که ز هر دل تا دل آمد روزنه

This couplet appears in the story of the lover's encounter with the Sadr-e Jahan. The preceding verses speak of how love, like a tree's branches reaching to the sky, can grow in the heart. Here, Rumi describes the Sadr-e Jahan's inner state, portraying him as a figure whose heart is so open to divine love that it naturally overflows with forgiveness. The imagery of 'waves of forgiveness' (موج می‌زد عفو گنه) suggests a powerful, almost uncontrollable surge of compassion. The second hemistich, 'For from every heart to another, a window opens' (که ز هر دل تا دل آمد روزنه), is a profound Sufi insight. It asserts that hearts are not isolated entities but are inherently interconnected, with 'windows' (روزنه) allowing for the transmission of feelings, intentions, and divine grace. This mutual permeability means that when love or a desire for forgiveness arises in one heart, it can resonate and find a path to another, facilitating reconciliation and understanding. It also implies that the love that arises in the lover's heart is mirrored by a responsive love in the beloved's heart, a theme Rumi explores further in subsequent verses.
