33.33

預修齋　普廣菩薩白佛言。若善男女未終之時。逆修生七然燈懸旛請僧（即僧次請供也）轉經（略舉此四為例）得福多否。佛言。其福無量。又言。父母親族命終受苦。為其修福得福多否。佛言。七分獲一。緣前生不信道德故。若以亡者嚴身之具屋宅園林。以施三寶。可拔地獄之苦（隨願往生經）。

Pre-cultivation Retreat: Bodhisattva Samantaprabha addressed the Buddha, saying, 'If good men and good women, before their demise, cultivate retroactively their living sevens, light lamps, suspend banners, invite monks (that is, inviting them in rotational order to offer alms), and recite scriptures (briefly citing these four as examples), will they obtain much merit?' The Buddha said, 'Their merit will be limitless.' He also said, 'When parents and relatives die and undergo suffering, if one cultivates merit for them, do they obtain much merit?' The Buddha said, 'They obtain one part in seven, because in their previous life they did not believe in morality. If one donates the deceased's personal adornments, houses, or gardens and groves to the Three Jewels, one can pull them out of the suffering of the hells' (Suiyuan wangsheng jing).
