Only Love Can Understand the Secrets of God (Poetry) ~ Maulana Rumi

Love sickness1 is clearly shown by the heart's misery.

There isn't any sickness like the sickness of the heart.

The "sickness" of the lover is distinct from other illnesses. 

Love is the astrolabe of the secrets of God.

Whether being a lover is from this or that origin,

Eventually it is our guide to that (Divine) Origin.

Whatever I say about Love, (in regard to) description and explanation,

 when I reach Love (itself) I am ashamed of that [inadequate description].

(For) although the explanation of the tongue is (an excellent) illuminator,

Yet Love (expressed) without the tongue is (much) clearer.

When the pen was hurrying in writing [descriptions],

 When it reached Love, it shattered against itself.

In (attempting) its explanation, the intellect lay down like a donkey (stuck helplessly) in the mud.

 (Only) Love (itself) spoke(the real) explanation of both love and being in love.

The sun is the demonstration of the sun.

if you need proof,seek it) from (the sun) -- (and) don't turn (your) face away!
