The books say (e.g., DhA.i.117) that Anuruddha became an Arahant after listening to this sutta. There is no sutta of this name, but the reference is evidently to theAnuruddha Sutta (A.iv.227 ff), which the Buddha taught Anuruddha who was then dwelling among the Cetis in Pācīnavaṃsamigadāya.

Anuruddha was meditating on seven of the thoughts, when the Buddha appeared before him and taught him the eighth — that the Dhamma is for the precise and for one who delights in exactness, not for the diffuse or for him who delights in diffuseness. The Buddha later addresses the monks of Suṃsumāragiri and tells them of the eight thoughts of a great man.
