Continuing with the 3rd step of explaining the wisdom of the אידן in their choosing קדושה over קליפה, the רבי explains how it is not about making a choice for a better return, it is rather about purely choosing the King!

But not because it makes sense: the profundity of this choice, the רבי continues in the 4th step, is that it does not originate from intellect; it emerges from the נשמה.

At the same time, however, the מדרש calls the איד a "פקח", because this essential choice of the נשמה affects the שכל of the איד as well to choose as well.

How? Stay tuned...
