阿罗汉归依于佛，阿罗汉有恐怖，何以故？阿罗汉于一切无，行怖畏想住，如人执剑欲来害己，是故阿罗汉无究竟乐。
《胜鬘师子吼一乘大方便方广经》

An arhat, seeking refuge in the Buddha, is afraid. Why?An arhat lives in fear of the imminent state ofnothingness, as if it were a man holding a sword comingto cause him harm. Therefore, the arhat does not haveultimate happiness.
