sn51.11:1.1 At Sāvatthī.
sn51.11:1.2 “Mendicants, before my awakening—when I was still unawakened but intent on awakening—I thought:
sn51.11:1.3 ‘What’s the cause, what’s the reason for the development of the bases of psychic power?’
sn51.11:1.4 Then it occurred to me:
sn51.11:1.5 ‘It’s when a mendicant develops the basis of psychic power that has immersion due to enthusiasm, and active effort.
sn51.11:1.6 They think: “My enthusiasm won’t be too lax or too tense. And it’ll be neither constricted internally nor scattered externally.”
sn51.11:1.7 And they meditate perceiving before and behind:
sn51.11:1.8 as before, so behind; as behind, so before;
sn51.11:1.9 as below, so above; as above, so below;
sn51.11:1.10 as by day, so by night; as by night, so by day.
sn51.11:1.11 And so, with an open and unenveloped heart, they develop a mind that’s full of radiance.
