The Interdependence of All Things

From Poems from the Divan of Hafiz (14th century), by Hafez, translated by Gertrude Bell in 1897.

The conception of the union and interdependence of all things divine and human is far older than Sufi thought. It goes back to the earliest Indian teaching, and Professor Deussen, in his book on Metaphysics, has pointed out the conclusion which is drawn from it in the Veda. “The gospels,” he says, “fix quite correctly as the highest law of morality, Love thy neighbour as thyself. But why should I do so, since by the order of nature I feel pain and pleasure only in myself, not in my neighbour? The answer is not in the Bible (this venerable book being not yet quite free from Semitic realism), but it is in the Veda: You shall love your neighbour as yourselves because you are your neighbour; a mere illusion makes you believe that your neighbour is something different from yourselves. Or in the words of the Bhagaradgitah: He who knows himself in everything and everything in himself, will not injure himself by himself. This is the sum and tenor of all morality, and this is the standpoint of a man knowing himself a Brahman.”

(Bhagaradgitah is an alternate spelling of Bhagavad Gita)

Also:

The Sufis were forced to pay an exaggerated deference to the Prophet and to Ali in order to keep on good terms with the orthodox, but since they believed God to be the source of all creeds they could not reasonably place one above another; nay more, since they taught that any man who practised a particular religion had failed to free himself from duality and to reach perfect union with God, they must have held Mahommadanism in like contempt with all other faiths. “When thou and I remain not (when man is completely united with God), what matters the Ka’ba and the Synagogue and the Monastery?” That is, what difference is there between the religion of Mahommadan, Jew, and Christian?
