十七年。哈麻及禿魯帖木兒等陰進西天僧于帝。行房中運氣之術。號演揲兒法。揲兒法者華言大喜樂也。又進西蕃僧善祕密法者。帝皆習之。帝在位久怠於政事荒于遊宴。以宮女一十六人按舞。名為天魔舞。首垂髮數辮戴象牙冠。身被瓔珞。大江銷金長短裙襖雲肩合袖天衣緩帶鞋[革*(卄/(ㄇ@儿)/戍)]。各執加巴剌班之器。內一人執鈴杵奏樂。又宮女十一人。練推髻勒帕常服。或用唐帽窄衫。所奏樂用龍笛頭管小鼓箏𥯪琵琶笙胡琴響板。以宦者長安迭不華領之。遇宮中贊佛則按舞奏樂。宮官受祕密戒者得入。餘不得預　二十八年國除。

In the seventeenth year, Hama, Tulu Temür, and others secretly introduced a Western monk to the Emperor to practice the bedchamber breath-circulation arts, termed the Yansheer method. The 'Sheer method' is translated into Chinese as 'Great Joy'. They also introduced a Tibetan monk skilled in esoteric rituals. The Emperor practiced all of them. Having been on the throne for a long time, the Emperor grew negligent in government affairs and indulged in excursions and banquets. He had sixteen palace maidens perform a dance, called the Dance of the Heavenly Demons. Their hair hung down in several braids and they wore ivory crowns. Their bodies were adorned with necklace ornaments; they wore long and short skirts and jackets embroidered with gold, cloud-collars, robes with joined sleeves, flowing sashes, and shoes. Each held a kapāla vessel; one among them held a bell and vajra and played music. There were also eleven palace maidens with hair bundled in white silk turbans and ordinary dress, or wearing Tang-style hats and narrow-sleeved jackets. The instruments played included the dragon flute, touguan, small drum, zheng, qin, pipa, sheng, huqin, and clappers. The eunuch Chang'an Diebuhua supervised them. Whenever there was praise of the Buddha in the palace, they performed the dance and played music. Palace officials who had received esoteric precepts were permitted to enter; the rest could not participate. In the twenty-eighth year, the dynasty fell.
