Aura cleansing is a practice aimed at removing negative energies or blockages from a person's energy field, also known as the aura. This process is often associated with New Age and alternative spiritualities, where practitioners believe that maintaining a clear and balanced aura is essential for physical, emotional, and spiritual well-being. Techniques for aura cleansing can include meditation, visualization, sound therapy, or the use of crystals, all intended to restore harmony and vitality.
