仏教物語：布施と五戒を守る事の功徳および梵天勧請全１０回の8回

Because sacrificing money or wife or children is not as difficult as sacrificing your own body and suffering slowly like that, not like a quick death. So, the Brahma wanted to remind the Buddha of the reason why He wanted to become Buddha, and so much sacrifice He had done. So now He attained Buddhahood, He should not have forgotten what He wanted to do, liberate other beings, even though it’s difficult. Yes, so at least He should try. And the Brahma saw that there are some numbers of beings who are ready for this teaching, can be taught, and can be saved, so please don’t look at others, the ignorant group, but teach these who are ready to hear; so he kept repeating the sacrifice of Buddha.
