I think that there are many versions of Islam. This is just my opinion based on my observations. I think some forms are very close to pantheism. I think certain versions of Sufism (which can arguably be defined as Islamic Mysticism) are very similar to certain versions of pantheism. Here God is thought of as the love that one experiences, or even as the feeling of suffering that one experiences.
Here is a video. I am posting the translation below. Here the poet talks about God not as a supernatural creator, but as Earthly experiences.
http://www.youtube.com/watch?v=mKLRsd1OzREI saw my beloved in all I saw,
At times revealed, hidden at times.
Been familiar with the issue of faith,
I saw the face of my beloved in all I saw.
At times a possibility, at times imperative,
At times ephemeral, at times eternal.
Inspired by the wish to see Himself,
He made Himself into every form.
He is the one who sees and hears
I saw no one other then Him.
Laughed gleefully through blooming flowers,
Crooned in nightingale's melodious songs.
He took the forms of the candle and the moth,
And annihilated Himself in flames of His own.
At times claiming "I am the Truth",
Witnessed his head raised on the Cross.
O 'Niyaz' He was beyond the bounds of `You' and `Me',
And yet I see Him in every `You' and `Me'.
At times he behaved like unfamiliar,
At timed I found him familiar with the face.
At times he is the emperor in power,
At times seen with a mendicant's begging bowl.
At times, a devout worshipper,
Lord of rakes and drunkards at times.
At times in the beloved's attire,
He was seen throwing up His charms.
At times as a lover like 'Niyaz',
He was seen beating his breast and heart aflame.
What do you think of this kind of 'faith'?
