Tantra has two sanskrit meanings. Tanoti means expands & Trayoti means liberates. It is the system by which you liberate the purusha and prakriti. This has two major entities, nadi and chakra. Nadi is an important concept in Hindu philosophy. In the yoga theory, nadis are carry life force energies known as prana. Nadis are pathways or channels of prana in the system.There are 72,000 different ways in which the energy or prana moves. The chakra in sanskrit means wheel. The life is dependent on the energy which we drives from various things. All the physical and mental activities of the body are run by energy. These wheels of energy which are in continuous spinning parallel to our spine from the bottom of our tail bone, to a few inches above the crown of our head are called chakras.
