PHYSIOLOGY & NAMASMARAN Meru is a golden mountain that supports the heaven, earth and hell. It supports the three levels of consciousness. It also means Tartar range of mountains north of Himalaya. This golden mountain is analogous to the brain, which supports all the aspects of individual life. One of the meanings of the word Meru (Sanskrit) seems to be brain. Hence the vertebral column is called Meru danda (Column or Rod).
