Investigation as Way to Suprahuman Force!
The Blessed Buddha once said:
When a Bhikkhu develops the Ways to Force, that is enriched with
concentrated Investigation,
constructed by effort, by
thinking:
In this
way will my Investigation, neither
be too
slack, nor too tense,
it will
neither
be constricted internally,
nor scattered externally,
then he
dwells
experiencing both what is in front, & what is behind,
what is above, so
also below, so by day, so also by night! Therefore,
with a mind all
open & unrestricted, he
develops the dazzling bright
mind, which is
pervaded by its own internal luminosity... However:
What is Investigation, that is too slack?
Investigation joined with
sloppy carelessness is
called Investigation, that is too slack!
What is Investigation, that is too tense? Restless,
hurried, agitated
Investigation is
called an Investigation, that is too tense!
What is Investigation, that is constricted internally?
Investigation
done in laziness. This is Investigation that is constricted
internally!
What is Investigation, that is scattered externally?
Investigation
that in craving & urge is directed towards the five sense
pleasures.
This is called Investigation that is scattered &
diverted externally!
How does one dwell experiencing both the front & what is behind?
The perception of front
& back, is well attended to, & thereby well
comprehended, well considered, & well known by understanding...
This is Investigation, that knows both what is in
the front & back!
How does one dwell seeing as below, so above; as above, so below?
One reviews this very frame of body upwards from the soles of the
feet, & downwards from the tips of the hairs, enclosed by skin, as
full of many kinds of impurities: There are in this body:
Head-hairs,
body-hairs, nails, teeth, skin, flesh, sinews, bones, bone-marrow,
kidneys, heart, liver, pleura, spleen, lungs, intestines, mesentery,
vomit in the stomach, excrement, bile, lymph, pus, blood, sweat, fat,
tears, slime, spit, snot, joint fluid , and urine...This is Investigation,
that knows what is below, so
also above; as above, so also below...
How does one dwell as by day, so at night; as at night, so by day?
Here, at night a Bhikkhu trains the
Steps to Force that is enriched
with
concentrated Investigation,
constructed by effort, using
the
same
techniques, qualities, & aspects, as he trains during the day.
So does one abide
as by day, so at night; as by
night, so by day!
And how, does one dwell with a mind that is all open & unrestricted,
a dazzling bright mind, which is pervaded by its own luminosity...?
Here, friends, the perception of day-light is well attended
to & well
resolved upon by determination. It is in exactly this way, that one
dwells with a mind, that is all open & unrestricted, a dazzling bright
mind, which is pervaded by its own luminosity...
