sn.56.20 Saṁyutta Nikāya (Linked Discourses)
Real
“Mendicants, these four things are real, not unreal, not otherwise.What four?
‘This is suffering’ …
‘This is the origin of suffering’ …
‘This is the cessation of suffering’ …
‘This is the practice that leads to the cessation of suffering’ …
These four things are real, not unreal, not otherwise.
That’s why you should practice meditation …”
