Silāyupa Sutta
Silāyupa Sutta:Sāriputta tells the monks that when a monk is wholly freed,objects,sounds,scents,etc.,that come within the range of his senses,cannot overwhelm his mind.It is like a stone column ten cubits long,one half of it buried in the ground,which cannot be shaken by the wind.
The sutta was preached as the result of a conversation between Sāriputta andCandikāputta regarding the teachings ofDevadatta.A.iv.402f.
