To dance in prayer, to move in prayer, for those who are able, can bring the prayer, you, and the community so fully into life that you enter hitgashmiut, the experience of being transported into pure spirit, far beyond gashmiut, "materiality."

Rabbi Nahman of Breslov (1720-1810) recognized the ecstasy of hitgashmiut as an essential nutrient for human healing, especially for and to prevent depression. "Acquire the habit of singing a tune. It will give you new life and fill you with joy. Take on the habit of dancing. It will displace depression and dispel hardship."
