佛說觀佛三昧海經 3.8

3.8

“After the Buddha’s nirvāṇa, if disciples of the fourfold assembly perform this contemplation, they will eliminate the sins of ten kalpas of birth and death. In subsequent births, their mouths will always have the fragrance of utpala flowers, and whatever they proclaim, people will believe and accept, just as Śakra and the thirty-two devas are fully trusted by all. Contemplating in this way is called correct contemplation; contemplating otherwise is called incorrect contemplation.”
