What are khanika, Upacara and Appana Samadhi?

[Gabriel_L]

@Brahmali

There are other kinds of samādhi mentioned in the suttas, but they are fairly marginal compared to the jhānas. Most importantly perhaps, the samādhi of the eightfold path, sammāsamādhi, is defined as the four jhānas.

And, as Mikenz says, upacāra samādhi and khanika samādhi are not from the suttas

Hope the above helps.
