Aura is a subtle energy field that surrounds and permeates the human body. It is believed to contain information about a person's physical, emotional, mental, and spiritual well-being. Some people claim to be able to see or sense auras, using them to gain insight into a person's state of being. Auras are said to be influenced by thoughts, emotions, and experiences, and can change in color, shape, and intensity. Practices such as meditation, energy healing, and yoga are believed to help cleanse and balance the aura, promoting overall health and well-being.
