Everything in the world draws something to itself:
infidelity draws the faithless,
and goodness, the one who is rightly guided.
Both magnet and amber attract:
whether you are iron or straw, you will be drawn.
If you are straw, you will be drawn to the amber;
and if you are iron, you will be pulled to the magnet.
When anyone is not associated with the good,
he inevitably becomes a neighbor to the corrupt.
... Mathnawi IV:1633-1636, Mevlana Rumi
