We are just trying to control over the nature. In the present days you are trying to control over the space. You are trying to float imitation planets. So this tendency of controlling or creating is there because partially we have got that controlling tendency. But we should know that this tendency is not sufficient. We have the tendency of controlling over the material nature, lording it over the material nature, but we are not the supreme controller. So that thing is explained in the Bhagavad-gītā.
Then what is this material nature? The nature is also explained. The nature, material nature, is explained in the Bhagavad-gītā as inferior, inferior prakṛti. Inferior prakṛti, and the living entities are explained as the superior prakṛti. Prakṛti means which is controlled, which is under... Prakṛti, real meaning of prakṛti is a woman or a female. Just like a husband controls the activities of his wife, similarly, the prakṛti is also subordinate, predominated. The Lord, the Supreme Personality of Godhead, is the predominator, and this prakṛti, both the living entities and the material nature, they are different prakṛtis, or predominated, controlled by the Supreme. So according to Bhagavad-gītā, the living entities, although they are parts and parcels of the Supreme Lord, they are taken as prakṛti.
