"There are two types of relinquishment through cessation: relinquishment as giving up, and relinquishment as entering into. It gives up defilements and aggregates, thus it is relinquishment as giving up; cognizance enters cessation which is the nibbana principle thus it is relinquishment as entering into. These are the two kinds of relinquishment through cessation."
Nirodhavasena dve vossaggaa: pariccaagavossaggo ca, pakkhandanavossaggo ca. Kilesa ca khandhe ca pariccajatiiti, pariccaagavossaggo; nirodhanibbaanadhaatuyaa cittam pakkhandatiiti. Pakkhandanavossaggo nirodhavasena ime dve vossaggaa.

"When a monk has emerged from the cessation of perception & feeling, to what does his mind lean, to what does it tend, to what does it incline?"
"When a monk has emerged from the cessation of perception & feeling, his mind leans to seclusion, tends to seclusion, inclines to seclusion."
According to the commentary, "seclusion" here stands for Nibbana.
