In matters of work on the path of truth, one should isolate oneself from other people. This is because the path of truth requires constant strengthening, since it is against the view of the world. The view of the world is knowing and receiving, whereas the view of Torah is faith and bestowal. If one strays from that, he immediately forgets all the work of the path of truth and falls into a world of self-love.
