Prabhupāda: Avyāpara means a occupation, an occupation which is not fit for you. That is avyāpara. Avyāpara-suvyaparam. And one occupation which is not exactly fitting you, you do not know how to do it, so avyāpare suvyaparam yo kartu... If one wants to act in a business in which he is unable to do, then he is killed just like this fool monkey. Avyāpare suvyaparam yo naraḥ kartum icchati, sa-mulo hanyate. That foolish person is killed just like this monkey. The monkey's business was not to imitate the sawman, but he wanted to imitate. The result was that he was killed. So that is not expertness.
