長阿含經 8.p19

8.p19

“Sometimes, you keep your arms raised all the time, don’t sit on couches or mats, or crouch all the time. Sometimes, you cut your hair and fasten it to your beard, lie on thorns, lie on fruits and berries, or lie naked in cow dung. Sometimes, you bath three times a day or three times a night. You torment your bodies with these countless hardships. How is it, Nigrodha? Can such practices be called a pure teaching?”
