Every gross centre of the body has its astral centre. A clear knowledge of the gross body is of utmost importance as this Yoga deals with the centre of the astral body. In subsequent chapters you will find, therefore, a short description of the centres of the gross body and their corresponding centres in the Sukshma Sarira. You will find the descriptions of the astral centres and their connected functions in the physical body.
Kanda:
This is situated between the anus and the root of the reproductory organ. It is like the shape of an egg and is covered with membranes. This is just above the Muladhara Chakra.
All the Nadis of the body spring from this Kanda. It is in the junction where Sushumna is connected with Muladhara Chakra. The four petals of the Muladhara Chakra are on the sides of this Kanda and the junction is called Granthi-Sthana, where the influence of Maya is very strong. In some Upanishads you will find that Kanda is 9 digits above the genitals.
Kanda is a centre of the astral body from where Yoga Nadis, subtle channels, spring and carry the Sukshma Prana (vital energy) to the different parts of the body. Corresponding to this centre, you have ‘Cauda equina’ in the gross physical body.
The spinal cord extending from the brain to the end of the vertebral column tapers off into a fine silken thread. Before its termination it gives off innumerable fibres, crowded into a bunch of nerves. This bunch of nerves is ‘Cauda equina’ in the gross body. The astral centre of ‘Cauda equina’ is Kanda.
