Ekottaragama (Sanskrit fragments) 9.6.4

9.6.4

爾時，世尊告諸比丘：「我恒觀見一人心中所念之事，如屈伸臂頃而生天上。所以然者，由善心故；已生善心，便生天上。」

It was then that the Bhagavān addressed the monks, “When I continuously examine the things that a person thinks about in their mind, I see: ‘This person will be born up in Heaven in the time it takes to flex their arm.’ Why is that? It’s because of their good mind. Having given rise to a good mind, they’ll be born up in Heaven.”
