In another Buddhist text "Majjhima Nikāya", the Buddha criticizes Jain emphasis on the destruction of unobservable and unverifiable types of karma as a means to end suffering, rather than on eliminating evil mental states such as greed, hatred and delusion, which are observable and verifiable. In the Upālisutta dialogue of this "Majjhima Nikāya" text, Buddha contends with a Jain monk who asserts that bodily actions are the most criminal, in comparison to the actions of speech and mind. Buddha criticises this view, saying that the actions of "mind" are most criminal, and not the actions of speech or body. Buddha also criticises the Jain ascetic practice of various austerities, claiming that he, Buddha, is happier when "not" practising the austerities.
