Major Chakras Are Eight, Not Seven - The Ancient Medical Wisdom of Thamizh

Generally, it is said that chakras are the energy centers in the body, there are many chakras out of which seven are important and that every chakra is associated with an endocrine gland.

According to Thirumoolar, an ancient saint from Tamizh Nadu, who lived at least 3000 years ago, major chakras are eight in number. In his work, Thirumanthiram, he has very clearly stated that these eight chakras are endocrine glands.

Endocrine Glands and Health

Endocrine glands secrete hormones directly into the blood thereby aiding in hormones reaching the cells in the body. Proper functioning of endocrine glands supports metabolism, healthy functioning of organs, reproduction and also supports mental health.

The Eight Endocrine Glands

Given below are endocrine glands and their important functions:

Pineal Gland

Regulates sleep-wake cycle

Hypothalamus Gland

Regulates body temperature, appetite and sleep-wake cycle

Pituitary Gland

Secretes hormones that promote growth and reproduction. It supports brain health, improves breast milk production. Most importantly, it regulates all endocrine glands.

Thyroid and Parathyroid Glands

Thyroid Gland plays a vital role in metabolism. It regulates body temperature and supports energy. Parathyroid maintains calcium levels in bones and blood.

Thymus Gland

Thymus gland is active till a child attends its puberty. This gland secretes hormones which support healthy growth of T cells, which are essential to boost immunity.

Adrenal Gland

Adrenal gland secretes hormones that regulate blood pressure, heart beat and fight or flight response to stressful situations.

Pancreas Gland

Pancreas gland controls blood sugar levels. It promotes digestion.

Much Before Recorded History and Much Ahead of Time - Thirumoolar and Ancient Medical Wisdom of Thamizh

One of the most important evidences to prove that Thamizh people are the most ancient people is the book Thirumanthiram authored by Thirumoolar. 

In 2-nd century, Greek Physician and Philosopher Galen writes about pineal gland. He also states that few others before him have mentioned pineal gland but he differed from those ahead of him in the function of pineal gland. Taking into account the appearance and its role in supporting local blood vessels, he says he believes it to be a gland. He also names the gland pineal owing to its pine-shaped structure. The impact of his knowledge and research on medical theories was such that it served as a guidance to physicians and researchers almost till mid 17-th century. 

Till the early 19-th century, there were no significant findings on the functioning of pineal gland. During the late 19-th century, it was suggested that pineal gland was the seat of soul and spirituality; it was also believed that it was the third eye mentioned in ancient texts. It was also suggested during this period that pineal gland might be an endocrine gland.

It was only during 20-th century, in the year 1958 did modern medicine discover that pineal gland secretes melatonin, which regulates circadian rhythm. 

These are the highlights we learn from the above-mentioned facts:

  • Though pineal is mentioned by few before 2nd century, it was only during 2nd century that the notion that pineal could be a gland was suggested. It was also named pineal owing to its structure during this period.
  • It was only during 19th century, the notion that pineal gland could be an endocrine gland was proposed. It was also proposed that pineal could be the Third Eye and the seat of consiousness.
  • It was only during 20th century, in the year 1958, modern medicine was able to determine that pineal is an endocrine gland and that it secretes melatonin which regulates circadian rhythm. 


Why do we say Thamizh is the most ancient of all? The accuracy of anatomical science of a race serves as a measure to the richness of its ancient medicine system. Any civilization with rich ancient medical knowledge and possesses wealth of knowledge in anatomical science is naturally a very ancient race.

While relentless efforts have been made starting with Greek philosophers of the 2nd century till the researches of modern science, to determine about pineal gland and its functions, Thirumoolar who lived thousands of years ago, has not only mentioned about pineal gland but also has written about its structure, location and its functions:

  • Thirumoolar mentions pineal as Eesan.
  • In the 14-th verse of Thirumanthiram, Thirumoolar mentions that pineal is the gat of sub-conscious mind.
  • In the 36th verse, he says that pineal secretes elixir of life. He mentions melatonin as the elixir of life. 
  • In the 16th verse of Thirumanthiram, Thirumoolar says that pineal is cone shaped. He also says that pineal, pituitary and hypothalamus are located under a structure that is shaped like the stigma of golden shower flower. This shape he is referring to is called corpus callosum by modern medicine.

Have a look at the golden flower shower's stigma.


Have a look at the shape of corpus callosum.


It is very much evident from the above information that Thirumoolar possessed excellent knowledge on anatomical science which is only reflective of how ancient Tamil race is. 

The above information is extracted from the book Thirumoolar Thirumanthiram - Thonmaiyin Meeteduppu - Kadavull Vaazthu authored by Dr. S.R. Thamizharasu.

  • Similar to Keezhadi excavations which bring to light the rich past of the Thamizh civilization, Thirumoolar's Thirumanthiram draws our attention to the unbelievably rich knowledge possessed by ancient Thamizh civilization in the field of medicine. It will be only right to say that Thirumoolar would have been the world's first anatomical scientist.
