Seven More at Most
An individual who has become a Streamwinner is said to have seven more lives to live at most.
There is some controversy as to the exact meaning of this statement. Some say it means a literal seven more lifetimes, sometimes as a human, sometimes as a diety; never below the human [manusa] realm.
It is also possible, and in the context of what amounts to the most difficult quest in the world, reasonable, that the idea is a finite number of rebirths. Satta, meaning seven, is based on the idea of a large (over 3) finite number.
Both ideas leave more room for doubt than is the usual case in a doctrine of the Buddha.
But here we have a definition of Eight Sorts of ('real' or 'wise' or 'good') Men and what makes them so:MAKE THE ARGUMENT THAT THE SEVEN REMAINING BIRTHS ARE THE STAGES FROM Enjoying the fruits of streamwinning to enjoying the fruits of Arahantship.
