We should also study his teachings that are based on the activities prior to the twentieth of Marcheshvan, then they may be left with nothing to accomplish on the actual day. (Firstly, we could only wish that such a matter could be our only “concern”...)
Further, the truth is that even after having toiled in the above for four full days, from Sunday until Wednesday (the twentieth), G-d will certainly grant additional power to enable us to engage in these matters with far greater strength. Treat divine service like a business: G-d’s empowerment resembles the manner of mortal wealth accumulation. Upon obtaining one’s originally desired figure, he is not satisfied. Rather, he immediately raises his desired profit margin to a higher figure. This analogy rings especially true in the spiritual sense: when we expend all our strength in divine service, G-d immediately grants even greater ability—and all the more so in light of the approaching auspicious day, the twentieth of Marcheshvan, when there is an incomparable elevation (see below, fn. 16).
