Pesach

The Rebbe stated that on Pesach one should cry out in davenning.
(Likkutei Moharan I, 201)

Like his saintly great-grandfather, the Baal Shem Tov, the Rebbe did not eat gebrokhts. However, in the Breslov community this chumrah is not taken to extremes. This is due to the Rebbe’s remarks about not taking on chumros yeseiros (excessive stringencies). Therefore, although most Breslovers refrain from gebrokhts, those who have a previous custom to eat gebrokhts are not obligated to change.
(Re. Rabbi Nachman’s attitude about chumros yeseiros, see Sichos ha-Ran (English: “Rabbi Nachman’s Wisdom,” Breslov Research Institute), section 235. This seems to have been the prevailing view in the circle of the Baal Shem Tov; cf. Rabbi Pinchas of Koretz, Imrei Pinchas ha-Shalem [Frankel edition, Bnei Brak 2003], vol. I, “Pesach,” sec. 170-173, that Reb Pinchas was opposed to excessive stringencies except on Pesach, and even then limited himself to those mentioned in the Shulchan Arukh.)

The Rebbe stated that reciting the Haggadah in a loud voice (be-kol ram) is a form of tikkun ha-bris, rectification of the Covenant.
(Likkutei Moharan I, 20:10)

Shevi’i shel Pesach is one of the five times of the year that Breslover Chassidim are particular to daven together ki-vasikin, following the custom of the Baal Shem Tov.
