“Therefore, o monks, do not brood over the world as to whether it is eternal or temporal, limited or endless …. Such brooding, O monks, is senseless, has nothing to do with genuine pure conduct (s. ādibrahmacariyaka-sīla), does not lead to aversion, detachment, extinction, nor to peace, to full comprehension, enlightenment and Nibbāna, etc.” (S.LVI, 41).
