英语听力：自然百科 圣河之旅 The Nile尼罗河—18

（单词翻译）

 Rising up alongside confluence¹ is the Khartoum, the capital of Sudan. I'd arrived in the city on a Friday. Islamic mystics known as Sufi were gathering² at the edge of the city to perform a weekly sunset ritual. It harks back to the earliest days of Islam on the Nile. These are whirling dervishes of Sudan. The journalist Ismal Kushkush was at hand to help me understand this magical. It's fairly chaotic³ spectacle. What are they doing? It's called zikr or rememberance. It's a way to purify the heart by reciting the certain chants, certain poetry. To purify them, purifying the heart, does that mean effectly clensing the body of evil. Absolutely. Through remembering the Gods, through these recitations, that heart is purified from any evil. It becomes closer and in oneness with the Lord. As the Sufi spin to rhythmic⁴ chants of crowd, then enter into a kind of trance. Their meditative⁵ state is intensified⁶ by the  overwhelming fragrance⁷ of frankincense. That's beautiful, beautiful smell.
