The word "chakra" literally means spinning wheel.
Yoga maintains that chakras are center points of energy, thoughts, feelings, and the physical body. According to yogic teachers, chakras determine the way people experience reality through emotional reactions, desires or aversions, levels of confidence or fear, and even physical symptoms and effects.
When energy becomes blocked in a chakra, it is said to trigger physical, mental, or emotional imbalances that manifest in symptoms, such as anxiety, lethargy, or poor digestion.
Asanas are the many physical positions in Hatha yoga. People who practice yoga use asanas to free energy and stimulate an imbalanced chakra.
There are seven major chakras, each with their own focus:
Sahasrara: The "thousand-petaled" or "crown" chakra represents the state of pure consciousness. This chakra is located at the crown of the head, and the color white or violet represents it. Sahasrara involves matters of inner wisdom and physical death.
Ajna: The "command" or "third-eye chakra" is a meeting point between two important energetic streams in the body. Ajna corresponds to the colors violet, indigo, or deep blue, though traditional yoga practitioners describe it as white. The ajna chakra relates to the pituitary gland, which drives growth and development.
Vishuddha: The color red or blue represents the "especially pure" or "throat" chakra. Practitioners consider this chakra to be the home of speech, hearing, and metabolism.
Anahata: The "unstruck" or "heart" chakra relates to the colors green and pink. Key issues involving anahata include complex emotions, compassion, tenderness, unconditional love, equilibrium, rejection, and wellbeing.
Manipura: Yellow represents the "jewel city" or "navel" chakra. Practitioners connect this chakra with the digestive system, as well as personal power, fear, anxiety, developing opinions, and tendencies towards an introverted personality.
Svadhishthana: Practitioners claim that the "one's own base" or "pelvic" chakra is the home of the reproductive organs, the genitourinary system, and the adrenal gland.
Muladhara: The "root support" or "root chakra" is at the base of the spine in the coccygeal region. It is said to contain our natural urges relating to food, sleep, sex, and survival, as well as the source of avoidance and fear.
