Kesi Sutta, what is an untamable person?

> "It is true, Kesi, that it's not proper for a Tathagata to take life. > But if **a tamable person** doesn't submit either to a mild training or to > a harsh training or to a mild & harsh training, then the Tathagata > doesn't regard him as being worth speaking to or admonishing. His > knowledgeable fellows in the holy life don't regard him as being worth > speaking to or admonishing. This is what it means to be totally > destroyed in the Doctrine & Discipline, when the Tathagata doesn't > regard one as being worth speaking to or admonishing, and one's > knowledgeable fellows in the holy life don't regard one as being worth > speaking to or admonishing." AN 4.111 Just so, is this subtle language? What then is an untamable person? Is it a being like an animal, who does not have access to Dhamma, or is it a being who has access to it, but disregards it out of hand, or something in between!?
