"At the twilight, a moon appeared in the sky;
Then it landed on earth to look at me.
Like a hawk stealing a bird at the time of prey;
That moon stole me and rushed back into the sky.
I looked at myself, I did not see me anymore;
For in that moon, my body turned as fine as soul.
The nine spheres disappeared in that moon;
The ship of my existence drowned in that sea."
Rumi's Divan Shams Tabrizi, 649:1-3,5
