本論文從說一切有部的角度探討部派佛教對「煩惱」的看法。《阿含經》裡的「煩惱」，在有部的論書中多以「隨眠」為名。隨眠有多種定義，包括六隨眠、七隨眠、十隨眠、十二隨眠、九十八隨眠。九十八隨眠整合了修行的方法，包括了「見所斷」及「修所斷」。見所斷有隨信與隨法兩種修行方向，分別以純信以及如理作意兩種方式修行。本論文並依據《品類足論》內容，發現修所斷仍是以五力、四念住為主要方法，並以五蘊為修行標的。

In this paper, the meaning of defilement in Sarvāsti-vāda School is explored. In Sajyuktāgama, it is called defilement. In Abhidhamma books, in most cases, it is called anusaya. There are several different types of anusaya, including 6-anusaya, 7-anusaya, 10-anusaya, 12-anusaya and 98-anusaya. In 98-anusaya, the practice techniques are included in the definition of 98-anusaya. The two included techniques are "cut off in the path of seeing" and "cut off in the path of cultivation". The path of seeing has two approaches: believing action and reasoning action. The path of cultivation is based on the 5 power and 4 stations of mindfulness with 5 aggregates as the target.
