When you are old and grey and full of sleep, And nodding by the fire, take down this book, And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace, And loved your beauty with love false or true, But one man loved the pilgrim soul in you, And loved the sorrows of your changing face; And bending down beside the glowing bars, Murmur, a little sadly, how love fled And paced upon the mountains overhead And hid his face amid a crowd of stars.
The furthest distance in the world Is not between life and death But when I stand in front of you Yet you don't know that I love you.
The furthest distance in the world
Is not when I stand in front of you Yet you can't see my love
But when undoubtedly knowing the love from both Yet cannot be together.
The furthest distance in the world Is not being apart while being in love But when I plainly cannot resist the yearning Yet pretending you have never been in my heart. The furthest distance in the world Is not struggling against the tides But using one's indifferent heart To dig an uncrossable river For the one who loves you.
倚窗远眺,目光目光尽处必有一座山,那影影绰绰的黛绿色的影,是春天的颜色。周遭流岚升腾,没露出那真实的面孔。面对那流转的薄雾,我会幻想,那里有一个世外桃源。在天阶夜色凉如水的夏夜,我会静静地,静静地,等待一场流星雨的来临…
许下一个愿望,不乞求去实现,至少,曾经,有那么一刻,我那还未枯萎的,青春的,诗意的心,在我最美的年华里,同星空做了一次灵魂的交流…
秋日里,阳光并不刺眼,天空是一碧如洗的蓝,点缀着飘逸的流云。偶尔,一片飞舞的落叶,会飘到我的窗前。斑驳的印迹里,携刻着深秋的颜色。在一个落雪的晨,这纷纷扬扬的雪,飘落着一如千年前的洁白。窗外,是未被污染的银白色世界。我会去迎接,这人间的圣洁。在这流转的岁月里,有着流转的四季,还有一颗流转的心,亘古不变的心。
