The instruction of our Sages that one should make a point to study [Torah] with a companion is well-known. Surely he can find a chavrusa (study partner) in the place where he lives. It is possible that [in the past] the circumstances did not suit his needs in this regard – that is, either he had no chavrusa, or the individual was not a fitting chavrusa. This detracts from the success of one’s learning. It is obvious that even if one has no chavrusa, it is still necessary to learn Torah. It is also clear that despair and low spirits do not come from “the side of kedusha.” As we see with our own eyes, this is not the way to inspire diligence, as is explained in several sources, including the Tanya.
