Starting from the bottom of the spine, these are –
| 1. | First Center | – Mooladhara Chakra |
| 2. | Second Center | – Swadhishthana Chakra |
| 3. | Third Center | – Manipura Chakra |
| 4. | Fourth Center | – Anahata Chakra |
| 5. | Fifth Center | – Vishudha Chakra |
| 6. | Sixth Center | – Agya / Ajna Chakra |
All these chakras are called Kamal (lotus) and the nerves, which originate from these centers, are called the Kamal-dal.
The mind and prana are deeply associated with each other. By holding the breath the mind is also held. With concentration of mind in any one of these chakras, a particular activity is experienced in the prana-nadis (channels) and in this way the activated nerves enhance the concentration of the mind further.
