Comm. NT: 15.
Indriyasaṃvarasīlavaṇṇanā

“As the elder was going along (occupied) only in keeping his meditation subject in mind, since noise is a thorn to those in the early stage, he looked up with the noise of the laughter, (wondering) ‘What is that?’
‘Perception of foulness’ is perception of bones;
for the elder was then making bones his meditation subject.
The elder, it seems as soon as he saw her teeth-bones while she was laughing, got the counterpart sign with access jhāna because he had developed the preliminary-work well. While he stood there he reached the first jhāna. Then he made that the basis for insight, which he augmented until he attained the paths one after the other and reached destruction of cankers”

Nyanamoli thera	[Wondering] “What is that?” the elder looked up and finding in the bones of her teeth the perception of foulness (ugliness), he reached Arahantship.15
