下阕起三句：“今古恨，几千般，只应离合是悲欢？”这里的“离合”和“悲欢”是偏义复词。由于题目“送人”与下阕头句“今古恨”，的情景的规定，所以“离合”，就只取“离”字义，“悲欢”就只取“悲”字义。上阕写送别，下阕抒情本应该是以“别恨”为主调的，但是作者笔锋拗转，说今古恨事有几千般，岂只离别一事才是堪悲的？用反问语气，比正面的判断语气更含激情。作词送人而居然说离别并不是唯一可悲可恨的事，显示出词的思想感情将有进一步的开拓。紧接着下文便又似呼喊又似吞咽地道出他的心声：“江头未是风波恶，别有人间行路难。”行人踏上旅途，“江湖多风波，舟楫恐失坠”（杜甫《梦李白》），但作者认为此去的遭遇比它更险恶。那是存在于人们心中、存在于人事斗争上的无形的“风波”；它使人畏，使人恨，有甚于一般的离别之恨和行旅之悲。“瞿塘嘈嘈十二滩，人言道路古来难；长恨人心不如水，等闲平地起波澜。”（刘禹锡《竹枝词》）其中的滋味，古人已先言之。作者在此并非简单地借用前人的诗意，而有他切身的体会。他一生志在恢复事业，做官时喜欢筹款练兵，并且执法严厉，多得罪投降派，和豪强富家，所以几次被劾去官。如在湖南安抚使任内，筹建“飞虎军”，后来在两浙西路提点刑狱公事任内，即因此事实被劾为“奸贪凶暴”、“厉害田里”而被罢官。这正是人事上的“风波恶”的明显例证。作者写出词的最后两句，包含了更多的伤心经历，展示了更广阔、更令人惊心动魄的艺术境界，情已淋漓，语仍含蓄。李白《行路难》的“欲渡黄河冰塞川，将登太行雪满山”，同此悲愤；白居易《太行路》的“行路难，不在水，不在山，只在人情反覆间”，正可说明悲愤的原因和实质。　　这首小令，篇幅虽短，但是包含了广阔深厚的思想感情，它的笔调深浑含蓄，举重若轻，不见用之迹而力透纸背，显示辛词的大家气度。延伸阅读（英文版）：
