We never know the value of what we have until we lose it. There is no medicine for regret in this world. Everything is already gone when we begin to regret. However, for a Buddhist practitioner, there is a cure for regret reciting the Eighty-Eight Buddhas Great Repentance.
人总是在失去的时候才猛然醒悟。世界上没有后悔药，当我们后悔的时候，一切已经离我们而去。学佛人学佛之后拥有了后悔药， 那就是《礼佛大忏悔文》。
