孤独的舞者

蒋智润

①秋天,草地上一片寂静,萧瑟冷清。大地上积满了落叶,枯败的叶子蜷缩着,如一张张满是皱纹的脸疲倦地向上张望着。阳光下,小草儿如漂洗过的白银一般,浅黄浅黄的,迎着秋风簌簌作响。四下里静悄悄的,一切都显得无精打采的,凛冽干燥的寒风暗示着这个季节并不属于脆弱的生命。

②然而,在绝望的阴影里似乎总是潜伏着那么一丝愉悦的惊喜。瞧去!不远处一只小小的蝴蝶,一身洁白,半透明的翅膀正不紧不慢地拍打着,宛若一朵飞舞着的雪花,细小的身子忽上忽下回旋跳跃着。一忽儿,轻轻地落在草叶尖上,吻一吻,旋即又飞走了。我想,它的内心该是被某种热切的渴望敦促着吧,孜孜以求,永不懈怠。

③枯黄的草地在我眼里忽然变成一方广阔的舞台,舞台上,这只小小的蝴蝶正孤独地旋着舞演一场独角戏。没有灯光,没有音乐,没有观众,没有掌声,孤独的舞者只是默默地奉献着它最美丽的舞姿,舞姿里有忧伤的美丽,舞姿里有优雅的欢乐。舞啊……舞啊……所有的绝望,所有的欢乐,所有的痛楚都融进这绰约的舞姿里。整个世界停顿下来,默默地注视着,万籁俱寂,周遭的大自然也莞尔笑了。

④一只小小的蝴蝶就这样征服了整个世界。夏日里,会有许许多多这样的蝴蝶,小小的,白白的,舞动在世界的各个角落,成群结队地飞过这个季节,不留下一丝痕迹。当花儿慢慢零落,生机勃勃的绿色也渐渐褪去,只留下孤零零的大地,光秃秃地裸露着,生命俱凋亡,仿佛干涸的生命之滩。夏日,兴旺茂盛的夏日,一天天远去了。这时,从某个不为人知的角落里,孤独的舞者悄然而至,开始享受它那姗姗来迟的短暂的生命。尽管,留给这个“不可理喻”的小生命的,并没有多少舒适与安慰,在这静默的季节里,它仍是这广漠舞台上唯一的主角。不知这小东西是否明白“美好东西的获得往往要做出巨大的牺牲”。代价的确是巨大的,秋天来临,日子一天天过去,寒冷一天天加剧,这一天天加剧的寒冷会无情地吞噬蝴蝶的生命。然而,重要的并不是生命的长度,而是其价值。

⑤不要怕在人生的舞台上做一个孤独的舞者!有多少人,在各自的生活中始终扮演着平庸卑微的角色,却从来没有拥有过自己的人生舞台?又有多少人,随波逐流,将自己独特的个性淹没在茫茫人海?舞步回旋,陌陌前路,何处蔷薇?而在世间的某个角落,一个含苞欲放的花骨朵儿正默默地等待着属于她的那只蝴蝶。有一天,他们相遇,娇嫩的花骨朵儿便张开她的怀抱热情地迎接那久久等待的客人旋着舞步缓缓而来。

    Hannah Levine decided she wanted to give hugs to all of the children and families in need at local hospitals.

    Because she couldn't give them one by one, Levine, then a sixth-grader, decided she would use her talents(才能) to do the next best thing. She began to knit(编织) hats, scarves, and blankets for families staying at the Ronald McDonald House at Stanford. Her creations also went to Bundle of Joy, a program that provides newborn baby items for families in need, and to Knitting Pals by the Bay, a local organization that provides hand-knitted caps to cancer patients.

    “I love to knit, and I thought it would be a great idea to make all these handmade items for kids and adults who need them. It would be like a hug for them,” Levine explained.

    Levine started the project about a year ago. “I think it's just really fun to do, and it keeps me busy,” said Levine, now 13.

    Once she got started, Levine realized that her project could be much bigger than the goods she was able to produce with just her own hands. So she sent emails to her school and communities(社区), asking for knitted donations(捐赠物) to the project she named “Hannah's Warm Hugs”. She also posted advertisements at Starbucks and other locations in her area. The warm goods began to gush in.

    “It was amazing; more strangers than people she knew started dropping donations at our door,” said Levine's mother, Laura Levine. “We ended up with this huge box of items she was donating.”

    The knitted items numbered in the hundreds. Levine made her first round of donations around Hanukkah (an eight-day Jewish holiday in November or December) and later received thank-you letters from the organizations. Levine is still knitting, and she said the project will continue.

    “It has turned into a bigger thing than she had thought,” her mom said. “It made her feel pretty good; it made us feel pretty good.”

《望大陆诗》

作者：于右任

“葬我于高山之上兮，望我大陆．

大陆不可见兮，只有痛哭．

故乡不可见兮，永远不忘．

天苍苍，野茫茫，山之上，国有殇．”注：于右任是参加过辛亥革命的国民党元老．1962年1月24日病重时在台湾写下《望大陆诗》．
