The actual analysis given in the ancient texts for the first two types
of kammadhaaraya is:
mahanto ca so puriso caati mahaapuriso (he is great also, a man also,
therefore "a great man").
satto ca so viseso caati sattaviseso (it is a being also, special also,
therefore "a special being" - lit. "a being special").
Another thing to note is the Great Mahasamana Jao who wrote the Thai
grammar text goes on at great length about how none of the ancient texts
really can agree on samaasa; some say this, some say that, and their
classifications differ.
