Sema

For Rumi the sema was an emotional relationship between man and God. in his Divan, he states:

Sema is only for the restless spirits -- so jump up quickly, why do you wait?
Do not sit there with your own thoughts -- if you are human, go to the Beloved.
Do not say, "Perhaps He does not want me."
What business has a thirsty man with such words?
Does the moth think about the flames? For Love's spirits, thought is a disgrace.
When the warrior hears the sound of the drum, at once he is worth ten thousand men.

-- Graze in the Meadows, Shems Friedlander

P.S. I'm no Sufi, but I read some of Rumi's work and I think he was absolutely brilliant with words and expressions, amongst many other things.
