Explanation of the line:
The line "had the leaves turn back due to steps of the walkers" is taken from the poem "The Road Not Taken" by Robert Frost. The poet is describing the two paths diverging in the woods, and how he chose the one less traveled. In this line, he is suggesting that the path he did not take may have been just as good, but people had walked on it and caused the leaves to turn back.

Interpretation:
This line suggests that the road less traveled is often the better choice, as it has not been worn down by the footsteps of others. The poet is suggesting that the path he did not take was still a good option, but may have been less appealing because it had been traveled by others. The leaves turning back due to the steps of the walkers can be interpreted as a symbol of the path being less natural and less authentic than the road less traveled.

Importance of the line:
This line is important because it highlights the theme of individuality and the importance of making one's own choices. The poet is suggesting that following the crowd may be easy, but it may not be the best option. By taking the road less traveled, the poet is able to assert his independence and make his own path in life. The line also emphasizes the idea that every choice we make has consequences, and the path we choose to take can have a significant impact on our lives.
