Sabbesaṃ vo, bhikkhave, subhāsitaṃ pariyāyena, api ca yaṃ mayā sandhāya bhāsitaṃ pārāyane metteyyapañhe:
Mendicants, you’ve all spoken well in a way. However, this is what I was referring to in ‘The Way to the Beyond’, in ‘The Questions of Metteyya’ when I said:
‘Yo ubhonte viditvāna,
majjhe mantā na lippati;
Taṃ brūmi mahāpurisoti,
The sage has known both ends,
and is not stuck in the middle.
He is a great man, I declare,
he has escaped the seamstress here (AN 6.61)
In Majjhesutta the Buddha give above verse from elsewhere.
Where to find pārāyana metteyyapañha? Is it Suttanipātapāḷi » Mettagūmāṇavapucchā (Snp 5.5)?
Are there any other suttas where the Buddha mention names of other suttas?
