Somewhat distressingly, Chasidim whose traditions include their own seforim seem often to prioritize them, when push comes to shove, over works of nigleh (="revealed," non-mystical knowledge, such as the written and oral Torah, and non-Chasidic machshava, mussar, and halacha). For example, Chassidus is studied in the morning in many Chasidic yeshivas, with nigleh study deferred to the afternoon; according to some, nigleh may not even be studied on Shabbos.
So I am wondering how these Chasidim stack seforim in perceived order of holiness. Do works of Chassidus go to the top of their piles? And since prayer is so important to Chasidim, is a siddur promoted from the bottom?
