Chakras are energy centers in the body that are believed to correspond to different physical, emotional, and spiritual aspects of our being. There are seven main chakras run from the base of the spine to the crown of the head, each with its unique qualities and associations. Balancing the chakras is thought to promote overall health and well-being.
The chakras are believed to be connected to the endocrine glands through the nadis, or energy channels, in the body. Each chakra is associated with a specific endocrine gland and is said to influence its function. For example, the root chakra is associated with the adrenal glands, the solar plexus ( pancreas), the heart chakra ( thymus),  the third eye chakra is associated with pituitary gland while the crown chakra is the pineal gland.
Reiki can balance the chakras by helping to remove blockages and promote the flow of positive energy throughout the body. Practitioners use their hands to channel energy into the areas of the body where the chakras are located, helping to restore balance and harmony to the body's energy system. This can lead to a range of physical, emotional, and spiritual benefits, including reduced stress and anxiety, improved sleep, and increased feelings of well-being.
