Shlach Lecha: Chapter 9
"Go up this way by the south"

We learn that God tells people to strive in the Torah and they will then recognize that it is available to support them, and they will be able to see if the just that live in the Garden of Eden got there by having overpowered their inclinations with strong effort, or if they studied the Torah day and night. They will be able to see what type of world it is and whether the Tree of Life is present forever. We hear warnings against those who think they can achieve the Garden of Eden with a lazy attitude and meaningless effort.
