Effect of Saptaswaras and Chakra Meditation
The physical body is ensheathed by auric field in which seven major chakras (invisible to the naked eye) are present. The seven chakras are Sahasrara, Ajna, Vishudhi, Anahatha, Manipura, Swadhistana and Mooladhara. Each chakra is associated with an endocrine gland and controls specific organs. Each swara resonates with one major chakra. When each note is sung concentrating on the shruthi, vibration of the corresponding chakra can be experienced. According to an ancient Indian text, Swara Sastra, the seventy-two melakarta ragas (parent ragas) control the 72 important nerves in the body. It is believed that if one sings with due devotion, adhering to the raga lakshana (norms) and sruti shuddhi, (pitch purity) the raga could affect the particular nerve in the body in a favourable manner.
