《资治通鉴·唐纪·唐纪四十》
代宗因此十分崇信佛教，经常在宫中设斋，供养一百多名和尚，有敌人前来就命令和尚宣讲《护国仁王经》，来祈祷免灾，敌人撤退后就赏赐给和尚丰厚的礼物。
上由是深信之，常于禁中饭僧百馀人；有寇至则令僧讲《仁王经》以禳之，寇去则厚加赏赐。
As a result, Daizong became deeply devoted to Buddhism. He often held Buddhist ceremonies in the palace, feeding more than a hundred monks. When enemies approached, he would order the monks to chant the "仁王护国经" to pray for protection from harm. Once the enemy had retreated, he would reward the monks with generous gifts.
