3.33 All beings follow their nature. Even the wise act according to their own nature. One should not come under the control of these two, because they are two stumbling blocks, indeed, on one's path of Self-realization. 3.35 One's inferior natural work is better than superior unnatural work. Death in carrying out one's natural work is useful.
Unnatural work produces too much stress.
Kaama is insatiable and is a great devil. Know this as the enemy. 3.38 Kaama, the passionate desire for all sensual and material pleasures, becomes anger if it is unfulfilled. As the fire is covered by smoke, as a mirror by dust, and as an embryo by the amnion, similarly the Self-knowledge gets obscured by Kaama. 3.39 O Arjuna, Jnana gets covered by this insatiable fire of Kaama, the eternal enemy of Jnani.
