sn40.4:1.1 “They speak of this thing called the ‘fourth absorption’.
sn40.4:1.2 What is the fourth absorption?
sn40.4:1.3 It occurred to me:
sn40.4:1.4 ‘It’s when, with the giving up of pleasure and pain and the disappearance of former happiness and sadness, a mendicant enters and remains in the fourth absorption, without pleasure or pain, with pure equanimity and mindfulness.
sn40.4:1.5 This is called the fourth absorption.’
sn40.4:1.6 And so … I was entering and remaining in the fourth absorption.
sn40.4:1.7 While I was in that meditation, perception and focus accompanied by pleasure beset me.
