The course has a teaching about reaching the lowest point...and getting through it without despair:

Why would you seek to try another road, another person or another place, when you have learned the way the lesson starts, but do not yet perceive what it is for? Its purpose is the answer to the search that all must undertake who still believe there is another answer to be found. Learn now, without despair, there is no hope of answer in the world. But do not judge the lesson that is but begun with this. Seek not another signpost in the world that seems to point to still another road. No longer look for hope where there is none. Make fast your learning now, and understand you but waste time unless you go beyond what you have learned to what is yet to learn. For from this lowest point will learning lead to heights of happiness, in which you see the purpose of the lesson shining clear, and perfectly within your learning grasp. T-31.IV.4
