sn40.10:9.1 It’s good to have experiential confidence in the teaching:

sn40.10:9.2 ‘The teaching is well explained by the Buddha—apparent in the present life, immediately effective, inviting inspection, relevant, so that sensible people can know it for themselves.’

sn40.10:9.3 It’s the reason why some sentient beings, when their body breaks up, after death, are reborn in a good place, a heavenly realm.
