What does this line mean I have found no exertion of the legs can bring two minds much nearer to one another mean.?

The line suggests that physical effort or actions (symbolized by "exertion of the legs") cannot bridge the emotional or intellectual distance between two people ("two minds"). It implies that mere physical presence or activity does not foster deeper understanding or connection; instead, it highlights the necessity of emotional or mental engagement to truly connect with someone. Ultimately, it reflects the idea that genuine connections require more than just being physically together.
