One aspect that all of these share is the presence of Karma as a currency. Karma, same as it was in EU4, can be modified by different factors, and gives different effects depending on its value:

Another very important aspect of Buddhist religions is the presence of various Buddhist Sects. Each religion has a variety of different sects, represented as International Organizations, and countries will belong to the sects of their own religion. Eastern Buddhism countries can belong to a maximum of 3 sects, while the rest of the religions allow for a maximum of a single sect.

Each sect has a value of Favor, representing the influence and support that sect has, as well as locations in which that sect is present. The sects also define themselves through a set of laws establishing their philosophy and teachings.

As long as sects have a high value of favor (over 60%), they will be able to expand their influence by adding more of their neighboring locations to the IO. Conversely, if sects have a low value of favor (less than 40%), they will start losing their locations. Sects will also lose locations if the dominant religion of the location is not the appropriate one. Sects can only gain or lose a single location at a time, though, so they will not completely disappear or extremely increase in size overnight, but it will be a gradual process.
