Rumi's Masnavi - And that sin in him is homogeneous with your sin: you must wash that (evil) disposition out of your own nature.

And that sin in him is homogeneous with your sin: you must wash that (evil) disposition out of your own nature.

Your evil character showed itself to you in him because he was (like) the surface of a mirror to you.

When you have seen your ugliness in the mirror, O Hasan, do not strike (a blow) at the mirror!

A lofty star is reflected in the water, and you cast earth on the star's reflexion, 3155

Saying, “This unlucky star has come into the water to overthrow my good luck.”

You pour upon it the earth of subjection, because on account of the resemblance you deem it to be the star (itself).

(When) the reflexion becomes hidden (from sight) and disappears, you think that the star is no more;

(But) the unlucky star is in the sky: ’tis in that quarter it must be cured (of its ill-luck);

Nay, you must fix your heart on that which is quarterless (illimitable); the ill-luck in this quarter is (only) the reflexion of the ill-luck in the realm where no quarters exist. 3160

Know that (all) gifts are the gift of God and are His bounty: ’tis the reflexion of those gifts that appears in (the world of) the five (senses) and the six (directions).
