Swami Veda Bharati said:
Man’s limbs are mere fan-blades whirling at the command of the energy flowing in the coil, the kundalini, or primal force. Here, think of a magnet on which you place a paper. Sprinkle some iron filings on this paper and they immediately arrange themselves in lines conforming to the magnetic force field. Each line in human personality is formed thus, along with the force-field of the life-force, the conscious-force.
