I found some years ago a very good document from an unknown author by googling “jars service nakshatra compatibility”, but that does not work any more. The document shows all nakshatras and interpretations for every interaction between all the nakshatras.
Very interesting for you who are interested in Astrological compatibility between nakshatras!
It seems now though it is available on Scribd from an author Purinaresh85 – the document is called Nakshatra Compatibility”(You can only search on scribd for it). Here is a link to the document: https://www.scribd.com/document/267003139/Nakshatra-Compatability .
I wish you a good read. Tell me if you also found that piece of document interesting:)
