《红楼梦》中“离恨天”一词只出现过三次,但它却把宝黛二人爱情的神话缘起、预寓和现实结局都贯穿起来了,在全书中起着重要的结构作用。《红楼梦》中“离恨天”的建构是对元曲和《西游记》等文学作品中“离恨天”的继承和超越。《红楼梦》中“离恨天”同元曲一样指向爱情的悲剧,却比之更具象更完整,成为宝黛爱情故事的特定意象;同《西游记》一样指向无欲世界,却剥去了其宗教外在形式,从内质上直接指向“色即空”的佛教哲理。同时它又凝聚着作家的辛酸泪,成为具有深邃意蕴的文学意象。而后来众多仿写小说中的“离恨天”未得个中三昧,远不能望其项背。 In “A Dream of Red Mansions”, the term “hate from heaven” only appeared three times, but it touched off the myth of both love and jealousy. Both preconditions and the actual ending were perfected and played an important structural role in the book. The construction of “Dianyingtiantian” in A Dream of Red Mansions is the inheritance and surpassing of “Dianyingtiantian” in the literary works such as Yuanqu and “Journey to the West”. The “hate day” in The Dream of the Red Mansions, like the same verse, points to the tragedy of love, but it is more concrete and complete than that. It becomes the specific image of Bao Dai’s love story. It is the same as “Journey to the West” Its religious external form points directly from the endogenous to the Buddhist philosophy of “color is emptiness.” At the same time, it condenses the bitter tears of the writer and becomes the literary image with deep meaning. Later, many imitation novel “hate the sky” without a Samadhi, can not expect its back.
