This sutta portrays two modes by which the Buddha responded to the controversial issues of his day. The first mode—illustrated by his contribution to the discussion on the ultimate cessation of perception—was to adopt the terms of the discussion but to invest them with his own meanings, and then to try to direct the discussion to the practice leading to the cessation of suffering & stress. The second mode—illustrated by his treatment of whether the cosmos is eternal, etc.—was to declare the issues as unconducive to awakening, and to refuse to take a position on them.
