"You must belong to those beef-cattle peoples down the road," I said. They said "Asalamalakim" when they met you, too, but they didn't shake hands. Always too busy: feeding the cattle, fixing the fences, putting up salt-lick shelters, throwing down hay. When the white folks poisoned some of the herd the men stayed up all night with rifles in their hands. I walked a mile and a half just to see the sight.

Hakim-a-barber said, "I accept some of their doctrines, but farming and raising cattle is not my style." (They didn't tell me, and I didn't ask, whether Wangero (Dee) had really gone and married him.)

What is the meaning of the word doctrines as it is used above?
