sn51.12:2.2 mental development …
sn51.12:2.3 inquiry, and active effort.
sn51.12:2.4 They think: ‘My inquiry won’t be too lax or too tense. And it’ll be neither constricted internally nor scattered externally.’
sn51.12:2.5 And they meditate perceiving before and behind:
sn51.12:2.6 as before, so behind; as behind, so before;
sn51.12:2.7 as below, so above; as above, so below;
sn51.12:2.8 as by day, so by night; as by night, so by day.
sn51.12:2.9 And so, with an open and unenveloped heart, they develop a mind that’s full of radiance.
sn51.12:2.10 When the four bases of psychic power have been developed and cultivated in this way they’re very fruitful and beneficial.
