​Chakra derives from the sanskrit word for 'Wheel' or 'Turning'. 

​Chakras, in Hindu metaphysical tradition and other belief systems, are centers of Prāṇa, life force, or vital energy. Life force is also known as QI or Chi in Chinese beliefs and Ki in Japanese. It can also be called ether and is known as the 5th or 6th element, depending on if you count metal as an element. Chakras correspond to vital points in the physical body i.e. major plexuses of arteries, veins and nerves. Texts and teachings present different numbers of chakra's. The numbers vary from 7 chakra to 8 or like the Egyptians believed 13. There can also be many other chakra's all throughout the body as well but the main 7 are most important. 
The concept of chakra features in tantric and yogic traditions of Hinduism and Buddhism.​​
