Karunanuyog is usually written as Karananuyog or Karnanuyog in Jain literature. It is one of the four Anuyogs of Jain scriptures, and it deals mainly with cosmology, calculations, the structure of the universe, karma, and related technical explanations. In simple words, it is the section of Jain study that explains how the universe and karmic laws are measured and described. ( jainworld.com)

If you want, I can also give its meaning in simple Gujarati/Hindi or list the four Anuyogs.
