The Theragāthā Commentary (ThagA.iii.184) says that the
incident of Moggallāna rocking the
Migāramātupāsāda with his thumb, at the
command of the Buddha, in order to frighten some novices who indulged in worldly
talk - is recounted in the Pāsādākampana Sutta.
This incident is recounted in the
Moggallāna Sutta of the Samyutta
It is also related in the Sutta Nipāta Commentary
(SnA..i.336f), as an introduction to the Utthāna Sutta.
