I cannot read Pali. I read the English translation of Walshe. In that those sentences are mentioned in DN28§7. Maybe it is helpful if i post the complete §7? Here is is:
7. ‘Also unsurpassed is the Blessed Lord’s way of teaching Dharnma in regard to the attainment of in four ways. Here, some ascetic or Brahmin, by means of ardour, endeavour, application, vigilance and due attention, reaches such
a level of concentration that he considers just this body -upwards from the soles of the feet and downwards from the crown of the head, enclosed by the skin and full of manifold impurities: “In this body there are head-hairs, body-hairs, nails, teeth, skin, flesh, sinews, bones, bone-marrow, kidneys,
heart, liver, pleura, spleen, lungs, mesentery, bowels, stomach, excrement, bile, phlegm, pus, blood, sweat, fat, tears, tallow, saliva, snot, synovic fluid, urine.” (as Sutta 22, verse5) That is the first attainment of vision. Again, having done this and gone further, he contemplates the bones covered with skin, flesh and blood. This is the second attainment. Again,having done this and gone further, he comes to know the unbroken stream of human consciousness as established both in this world and in the next.That is the third attainment. Again, having done this and gone still further, he comes to
know the unbroken stream of human consciousness that is not established either in this world or in the next.866 That is the fourth attainment of vision. This is the unsurpassed teaching in regard to the attainments of vision.. .
according note 866 (walshe) this last stream refers to the arahant
If you read about this stream of consciousnes, according not 865, it refers to vinnana-sota, a rare expression in the sutta’s according Walshe. So if you see vinnana-sota that is probably the location, Lal.
