his contemporaries under the guidance ofBasavanna, discussed
about human anatomy and physiology. Chennabasavanna deals with
it in detail in his Karana Hasige. The Chakras (nerve plexus)
are the basis of our study of human anatomy and physiology.
They have detected the' Bioplasmic energy' and mapped out in
detail exact flow of current in the body. They have named nine
chakras, which are the centres of energy. A brief account of
them is given here. Chakra literally means ' wheel'. Chakras
are the nerve centres offeree and consciousness. They correspond
to nerve plexus, ganglion, glands of physical
body. The chakras arc subtle, our insight
or our intuition enables us to experience them. Each chakra
controls particular field of activity and the component factors
of the body. Each chakra is related to a certain endocrine gland.
The chakras control the operation of the body and mind by
means of hormones. Like the higher glands controlling the lower glands, the higher chakras control the lower chakras.
Sharanas discuss about three portions of the brain in detail. They
call cerebral cortex by the name Brahmarandhra. It consists
of thousands of petals or groups of nerves. It is a part of the
intellectual aspect of God who dwells in the form ofJeeva (self).
This Jeeva is cal\edNishkala Linga. The central portion of
the brain is called Sikhachakra. This consists of three groups of
nerves (Lymbic system). In this part, Prana or life breath dwells
and is called Shoonya linga. The hind part of the brain is called
Paschimachakra which consists of a single nerve (Pineal body
). In this part self-luminous Soul dwells and is called Niranjana
Linga. Just below this part, spinal cord begins. Further sharanas
divided the nervous system of the entire body into six parts
as shown below.
