QUESTION: Is there evidence of meritorious acts in past lives?
ANSWER: The Lotus Sūtra, fascicle 2, chapter 3 on “A Parable” states, “He who believes in this sūtra in this life must have seen the Buddha, shown respect to Him, given offerings and listened to Him preach this sutra.” The sūtra also suggests in the tenth chapter on “The Teacher of the Dharma,” “Suppose there are those who, upon listening to even a verse or a phrase of the Lotus Sūtra, will rejoice even for a moment of thought after the extinction of the Buddha. (…) You should know that such persons made offerings to ten trillion Buddhas in previous lives.”
