This is a question about the different numbering systems, continuing to use the same example. I have read some threads that refer differences between SC and PTS numbering and think the two links in this entry are the most useful?
Back to the example, the DPPN gives these references for the Metta Sutta (not Karanīyametta Sutta): (KhpA.232 ff; cp. DhA.i.313 ff)
(‘ff’ means ‘and following’; wht does ‘cp’ mean?)
In total there are four numbers now for one text. Which systems do each of these four numbers belong to please?
I thank you for your patiences.
