Dictionary entries often have references to the Suttas using html like “SN.iii.159” on a grey background. How does one use these to navigate? They don’t seem to be links (for me), and searching SC using this form doesn’t hit on the intended sutta or passage.
The references mentioned in the PTS dictionary are those of the PTS volume & page numbers in the PTS editions of the pali canon.
Ideally they would be links but given the sheer volume of the PTS dictionary, this would be a huge job to make.
You can find the PTS volume & page numbers in the lists of the suttas. For instance “SN.iii.159” is in the Samyutta Nikaya, volume III, page 159. So if you look in the Samyutta Nikaya 22: SuttaCentral you can see this:
So your reference refers to SN 22.105 and SN 22.106. At the moment we do not have an English translation of these two suttas yet, but this should be ready in a few months when we launch the new website.
