The Elder Málunkyaputta is dissatisfied, feeling that the Buddha has not expounded to him various speculations concerning life and death and the nature of the world. He visits the Buddha at Jetavana and tells him of his disappointment. The Buddha points out to him that no promise was made regarding the elucidation of such problems and tells him it were fitter if he were to speculate by striving for deliverance. Málunkyaputta sees the error of his ways. M.i.426ff
