Definition - What does Majja Dhatu mean?
According to Ayurveda, the Sarira (body), Manas (mind), and Prana (life force) are all supported by tissues known as dhatu. Majja Dhatu refers to the nervous system, not limited only to the central nervous system of brain and spinal cord, but encompassing all nerve tissue and bone marrow.
Majja Dhatu is responsible for functions of the brain and nervous system, body strength, bone nourishment and mental or emotional state. A hectic lifestyle, poor diet, trauma, accident, insomnia and suppression of emotions are all causes of imbalance in the Majja Dhatu tissue.
Yogapedia explains Majja Dhatu
Ayurveda identifies seven dhatu or tissues within the human body: rasa dhatu (plasma), rakta dhatu (blood), mamsa dhatu (muscle), meda dhatu (fat), asthi dhatu (bone), majja dhatu (nervous tissue), and shukra dhatu (male reproductive tissue) or artava dhatu (female reproductive tissue).
Majja means marrow, but the term has become synonymous with the nervous system since it is encased in bone in the same way as bone marrow; for example, the brain within the skull or the spinal cord within the vertebrae. In order to produce Majja Dhatu in the body, air and water elements must be taken in balance.
Healthy Majja Dhatu is reflected by a healthy flow of Prana, or life force energy. Too much Majja Dhatu may cause heaviness of the eyes or body and oedema in the joints. Not enough Majja Dhatu can lead to weak bones, osteoporosis, low sperm count and dizziness. If Majja Dhatu is weak or low, it is recommended to eat walnuts and ghee.
