Dear Reb Eliezer,
To me Kedushas Levi is a stand alone sefer. Without knowing better, one who learns it well can be completely ignorant of it’s standing in the larger movement. Studying just Kedushas Levi will give plenty to strive for. But I do not think it will give a chassidshe feel to the uninitiated reader. Do you agree?
Although, there is an English edition that greatly expands the themes into structured chasidic thought. I’m aware there is an ongoing attempt to resurrect Reb Levi Yitzchok’s teaching’s in a more causative light. But that mostly reflects on real life aspects, as opposed to Chassidishe Seforim. Either way, I’m not to familiar with the contents of what they publish.
