《先知》是纪伯伦的巅峰之作，探讨爱与美、生与死等生命的奥秘。欧美评论家把《先知》和泰戈尔的《吉檀迦利》并称为东方最美妙的声音。纪伯伦称之为"我的第二次诞生，第一次洗礼"。《沙与沬》用格言阐释生命、艺术、爱情、人性，以"沙""泡沫"喻人似沙般微小、事物如泡沫般虚幻，寓意深刻，充满智慧，音韵妙曼，宛如天籁。(Prophet, the most popular works of Gibran, discusses mysteries of life, such as love and beauty, life and death. The European and American critics list Prophet and Tagore's Gitanjali as the most wonderful voice in the east. Gibran himself calls it "the birth of my second, baptism of the first". Sand and Foam interprets life, art, love and human nature with motto. "Sand" and "foam" is vivid expression of smallness of people like sand, and of illusory things like foam, which is of profound meaning, full of wisdom, phonologically beautiful like the music. )
