Muladhara, also known as the root chakra, is the first of the seven main chakras in the human body according to Hindu and Buddhist tradition. It is located at the base of the spine and is associated with the color red. It is associated with the earth element and represents our foundation and grounding. It is also associated with our basic survival instincts and is related to our physical body and its needs such as food, shelter, and safety. When this chakra is balanced, one may experience a sense of safety and security in their physical body and in the world. This chakra is associated with the adrenal glands and the skeletal system, as well as the sense of smell. When it is blocked, it can manifest as feelings of insecurity, fear, and instability.
