The "ten energy bodies" form the core of Kundalini Yoga. These are the subtle energy fields that surround a person and represent their fundamental qualities such as values, abilities, and emotional life. Kundalini Yoga includes body and breathing exercises as well as meditations, particularly with mantras, which specifically activate the flow of energy and allow individuals to develop spiritually and mentally more quickly and effectively. Ulrike Reiche explains the system of the "ten energy bodies" for the first time specifically for Western readers and encourages the integration of this spiritual practice into personal life.
