==== Spiritual qualities of the Niggun ====
The Rebbe Maharash: "When singing the Alter Rebbe's niggun, it is an opportune time for teshuvah, because it is an eis ratzon (favorable time) above."

The Rebbe Rashab: "When the niggun is sung with inner awakening, it is an opportune time for teshuvah and hiskashrus (connection to the Rebbe); and when the niggun is sung with purity of heart, after proper terumas hadeshen at Tikkun Chatzos, after saying Krias Shema at bedtime with authenticity, and after prayer with deep effort, one can effect a personal salvation in children and life."

The Rebbe Rayatz: "We have a promise that when the niggun is sung, whenever and wherever it may be, the Rebbe (Alter Rebbe) will hear it and feel it, at whatever high levels he may be. But this depends on the preparations of the receiver." When this niggun is sung at the Rebbe's farbrengens, the Rebbe emphasizes that it should be sung with great deliberation and deep seriousness.

The Rebbe instructed musician Jean Zeidel-Rudolf not to make changes to the niggun.
