The practice of Sufism is the intention to go towards the Truth, by means of love and devotion. This is called the tarigat, the spiritual path or way towards God. The sufi is one who is a lover of Truth, who by means of love and devotion moves towards the Truth, towards the perfection which all are truly seeking. As necessitated by love's jealousy, the sufi is taken away from all except the Truth.

This transcends mere logic, intellectual proof; rather it involves realization, revelation and witnessing. It's beyond words, mere social conventions. It is for the enlightened inner beings or souls, offers a way to the actualization of GOD and beyond.

How can you put the infinite into words, how can you capture the unbound? It is only to be realized. When the ealized one speaks, others can find a path.

Sufism is associated with self-expression even beyond words. There is music, poetry and so much. The core is LOVE.

Rumi is one of the most famous sufis.

Rumi used to tell a story of an elephant.
Six blind men once went to find out what an elephant is.
The first blind man touched the legs of the elephant, being a blind man he could only touch and not see. He touched the legs of the elephant and came to the conclusion that the elephant is like a big pillar or a tree; straight, round, long and strong with thick skin.
The second man touched the tail of the elephant and came to the conclusion that an elephant is like a rope with a brush at the end and it can move right and left very easily in air.
The third man touched the ear of the elephant and said, "Elephant is a flat animal, like a hand fan"
The fourth man who had touched only the trunk of the elephant said "No, the elephant is like a snake or a tree branch, rough on the surface and is hollow inside.
The fifth man who had touched its belly said "An elephant is like a big wall, but with curves here and there"
The sixth man who had touched only the tusk said "An elephant is like a pipe or spear and very strong"
After they found out they had disagreement, they went to a man who had eyes and had seen the elephant. Each explained his side of the story and asked him who was right among them.

The man who had seen the elephant said: "You are all partially correct, Elephant has features that you explained but it is much more"

According to Rumi, the moral is: The sensual eye is just like the palm of the hand. The palm has not the means of covering the whole of the beast.

The sufi says that witnessing the Ocean with the eye of a drop is impossible. However, when the drop becomes one with the Ocean, it sees the Ocean with the eye of the Ocean. So it's to be realized with the innerbeing, a deeper identity is discovered and lived.
