An Analysis of the Bases of Power
Iddhipāda-Vibhaṅga Sutta  (SN 51:20)

“These four bases of power, when developed & pursued, are of great fruit & great benefit. And how are the four bases of power developed & pursued so as to be of great fruit & great benefit?

“There is the case where a monk develops the base of power endowed with concentration founded on desire & the fabrications of exertion, thinking, ‘This desire of mine will be neither overly sluggish nor overly active, neither inwardly constricted nor outwardly scattered.’ He keeps perceiving what is in front & behind so that what is in front is the same as what is behind, what is behind is the same as what is in front. What is below is the same as what is above, what is above is the same as what is below. (He dwells) by night as by day, and by day as by night. By means of an awareness thus open & unhampered, he develops a brightened mind.

“He develops the base of power endowed with concentration founded on persistence…

“He develops the base of power endowed with concentration founded on intent…

“He develops the base of power endowed with concentration founded on discrimination & the fabrications of exertion, thinking, ‘This discrimination of mine will be neither overly sluggish nor overly active, neither inwardly constricted nor outwardly scattered.’ He keeps perceiving what is in front & behind so that what is in front is the same as what is behind, what is behind is the same as what is in front. What is below is the same as what is above, what is above is the same as what is below. (He dwells) by night as by day, and by day as by night. By means of an awareness thus open & unhampered, he develops a brightened mind.

“And how is desire overly sluggish? Whatever desire is accompanied by laziness, conjoined with laziness, that is called overly sluggish desire.

“And how is desire overly active? Whatever desire is accompanied by restlessness, conjoined with restlessness, that is called overly active desire.

“And how is desire inwardly constricted? Whatever desire is accompanied by sloth & drowsiness, conjoined with sloth & drowsiness, that is called inwardly restricted desire.

“And how is desire outwardly scattered? Whatever desire is stirred up by the five strands of sensuality, outwardly dispersed & dissipated, that is called outwardly scattered desire.

“And how does a monk dwell perceiving what is in front & behind so that what is in front is the same as what is behind, and what is behind is the same as what is in front? There is the case where a monk’s perception of what is in front & behind is well in hand, well-attended to, well-considered, well-tuned [‘penetrated’] by means of discernment. This is how a monk keeps perceiving what is in front and behind so that what is in front is the same as what is behind, and what is behind is the same as what is in front.

“And how does a monk dwell so that what is below is the same as what is above, and what is above is the same as what is below? There is the case where a monk reflects on this very body, from the soles of the feet on up, from the crown of the head on down, surrounded by skin, & full of various kinds of unclean things: ‘In this body there are head hairs, body hairs, nails, teeth, skin, flesh, tendons, bones, bone marrow, kidneys, heart, liver, pleura, spleen, lungs, large intestines, small intestines, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, skin-oil, saliva, mucus, fluid in the joints, urine.’ This is how a monk dwells so that what is below is the same as what is above, and what is above is the same as what is below.

“And how does a monk dwell by night as by day, and by day as by night? There is the case where a monk at night develops the base of power endowed with concentration founded on desire & the fabrications of exertion by means of the same modes [permutations] & signs & themes that he uses by day, and by day he develops the base of power endowed with concentration founded on desire & the fabrications of exertion by means of the same modes & signs & themes that he uses by night. This is how a monk dwells by night as by day, and by day as by night.

“And how does a monk—by means of an awareness open & unhampered—develop a brightened mind? There is the case where a monk has the perception of light, the perception of daytime [at any hour of the day] well in hand & well-established. This is how a monk—by means of an awareness open & unhampered—develops a brightened mind.

[The above discussion is then repeated for persistence, intent, & discrimination.]

“When a monk has thus developed & pursued the four bases of power, he experiences manifold supranormal powers. Having been one he becomes many; having been many he becomes one. He appears. He vanishes. He goes unimpeded through walls, ramparts, & mountains as if through space. He dives in & out of the earth as if it were water. He walks on water without sinking as if it were dry land. Sitting cross-legged he flies through the air like a winged bird. With his hand he touches & strokes even the sun & moon, so mighty & powerful. He exercises influence with his body even as far as the Brahmā worlds.

“He hears—by means of the divine ear-element, purified & surpassing the human—both kinds of sounds: divine & human, whether near or far.

“He knows the awareness of other beings, other individuals, having encompassed it with his own awareness. He discerns a mind with passion as ‘a mind with passion,’ and a mind without passion as ‘a mind without passion.’ He discerns a mind with aversion as ‘a mind with aversion,’ and a mind without aversion as ‘a mind without aversion.’ He discerns a mind with delusion as ‘a mind with delusion,’ and a mind without delusion as ‘a mind without delusion.’ He discerns a restricted mind as ‘a restricted mind,’ and a scattered mind as ‘a scattered mind.’ He discerns an enlarged mind1 as ‘an enlarged mind,’ and an unenlarged mind as ‘an unenlarged mind.’ He discerns a surpassed mind [one that is not at the most excellent level] as ‘a surpassed mind,’ and an unsurpassed mind as ‘an unsurpassed mind.’ He discerns a concentrated mind as ‘a concentrated mind,’ and an unconcentrated mind as ‘an unconcentrated mind.’ He discerns a released mind2 as ‘a released mind,’ and an unreleased mind as ‘an unreleased mind.’

“He recollects his manifold past lives [lit: previous homes], i.e., one birth, two births, three births, four, five, ten, twenty, thirty, forty, fifty, one hundred, one thousand, one hundred thousand, many eons of cosmic contraction, many eons of cosmic expansion, many eons of cosmic contraction & expansion, (recollecting,) ‘There I had such a name, belonged to such a clan, had such an appearance. Such was my food, such my experience of pleasure & pain, such the end of my life. Passing away from that state, I re-arose there. There too I had such a name, belonged to such a clan, had such an appearance. Such was my food, such my experience of pleasure & pain, such the end of my life. Passing away from that state, I re-arose here.’ Thus he remembers his manifold past lives in their modes & details.

“He sees—by means of the divine eye, purified & surpassing the human—beings passing away and re-appearing, and he discerns how they are inferior & superior, beautiful & ugly, fortunate & unfortunate in accordance with their kamma: ‘These beings—who were endowed with bad conduct of body, speech, & mind, who reviled the noble ones, held wrong views and undertook actions under the influence of wrong views—with the break-up of the body, after death, have re-appeared in a plane of deprivation, a bad destination, a lower realm, hell. But these beings—who were endowed with good conduct of body, speech, & mind, who did not revile the noble ones, who held right views and undertook actions under the influence of right views—with the break-up of the body, after death, have re-appeared in a good destination, a heavenly world.’ Thus—by means of the divine eye, purified & surpassing the human—he sees beings passing away and re-appearing, and he discerns how they are inferior & superior, beautiful & ugly, fortunate & unfortunate in accordance with their kamma.

“Through the ending of the effluents, he enters & remains in the effluent-free awareness-release & discernment-release, having directly known & realized them for himself right in the here & now.

“This is how these four bases of power, when developed & pursued, are of great fruit & great benefit.”
