How to understand Tagore's poem: "God finds himself in creating the world."

People have a sense of superiority and frustration about themselves. Basically, everyone thinks that he is excellent, and the God who made man can show his talents. People found that the world was beautiful and rich, so God created a beautiful world, which was so awesome and admirable.

God discovered himself through creation, just as man invented the steam engine, which promoted the process of civilization and made people know their own strength. The civilized world after the industrial revolution has also brought many troubles and crises to people, so they have found their own advantages and disadvantages, which is a favorable condition for them to know themselves. In my opinion, God and man are equal, because life is the same, and we know ourselves in survival.
