For comparison, I show B. Bodhi's translation first. There are several code phrases and cryptic words that don't make any sense on their own without explanation. In my SP-Fluent translation, I "spell out" some of those code phrases so the sutta is more comprehensible. See link to my site, for B. Bodhi's KN Nidd commentary section explaining the sutta, which I mostly agree with.
(Bhikkhu Bodhi trans.)
14 THE QUESTIONS OF POSĀLA
1112. “I have come in need with a question,”
(said the Venerable Posāla),
“to the one who points out the past,
who is without impulse, who has cut off doubt,
who has gone beyond all phenomena. (1)
1113. “I ask, Sakya, about the knowledge
of one for whom perception of form has vanished,
who has entirely abandoned the body,
who sees ‘there is nothing’
internally and externally:
how is such a one to be led?” (2) 
1114. “Directly knowing all stations of consciousness,
(Posāla,” said the Blessed One),
“the Tathāgata knows this one
remaining, who is liberated,
who has that as support. (3)
1115. “Having known the origin of nothingness
thus, ‘delight is the fetter,’
having directly known it in such a way,241
one then sees into it with insight.
This is the real knowledge of the brahmin,
one who has lived the spiritual life.” (4)
