龔自珍乃以思想名家，梁啟超在《中國近三百年學術史》盛讚其與魏源兩人同是清朝中葉重要思想家，其影響力下及光緒時期，乃至近代變革，是站在時代的轉折點上，引領著時代前行的領袖型人物。除此之外，其多方面的才華，同樣不可忽視，其於文學、藝術上成就不凡，值得研究。如其《定盦詞選》自成一格，破除文體的局限，運斤自如，既可抒情也可論道，呈現萬種風貌。本論文擬專就《定盦詞選》，探討龔自珍作為一個思想家，處在亂世之中，如何以宗教安頓自己的生命。除前言、結語之外，本文凡分三重點：首先論其詞中所述佛教思維及人生觀；其次探究其詞中所述宗教修行其及實質內涵；後論當他遇到生命中的靈魂伴侶時，以甚麼樣的態度去面對。如此周折於入世與出世之間的思想家、深情詩人，在詞的文體之中呈現最任性、真率的自我。
