Rumi on the observer and observed...

Shems 25:

Look on me, you who are my grave's companion,
On the night when you pass from shop and house.

You shall hear me cry out from the tomb, and know
Your presence was never far from my lively gaze.

As reason and intellect I'm within your heart,
At times of gladness, at times of distress.

Strange is the night when you hear a familiar voice
Escape the nip of an asp, or leap from an ant's bite!

As a gift, Love's intoxication will bring to your grave
Wine and mistress, candle and meats, sweets and incense.

At the hour when intellect's lamp is lit, what cries
Of praise go up from dead men in their tombs!

The dark earth of the graveyard is confounded by their noise,
By the din of Resurrection's drums, by the pomp of those risen.

They have torn their shrouds, and closed their ears in horror.
What is the mind and ear before this trumpet?

Look into your own eye, and make no mistake,
So that essence of seer and seen become one.

On whatever side you gaze, you shall see my form,
Whether you gaze upon self, or the mass that is visible. 

Shun distorted vision and heal your sight, for the evil eye
Will be distant from my beauty in that moment.

Beware, lest in error you see me in human form.
For the spirit is extremely subtle, Love is jealous.

What room is there for form, if what is felt extends beyond?
The soul's mirror reflects light that illuminates the world.

Had they looked for God instead of food and livelihood
Not a single blind man seated by the moat would be seen.

Since you have opened up a shop in our city as a dealer in amorous glances,
Then like light, deal out glances with closed lips.

I hold my peace and keep those who are unworthy in the dark;
You are all that is worthy: though for me the mystery is forever veiled.

Like the Sun of Tabriz, rise, rise towards the east;
See the star of victory, and the conqueror's banner!
