What did Adam smith mean when he wrote about he invisinble hand?

Adam Smith's concept of the "invisible hand" refers to the self-regulating nature of a free market economy, where individuals pursuing their own self-interest inadvertently contribute to the overall good of society. By seeking personal gain, producers and consumers make decisions that lead to efficient resource allocation and innovation. This metaphor suggests that individual actions, when guided by market forces, can lead to positive outcomes without the need for central planning. Ultimately, the invisible hand illustrates how personal motivations can align with societal benefits in a competitive marketplace.
