This is the nataraja concept of the world.
The world is built on rythms , the rythm of seasons, of day and night , of sleep and wakefulness , of breathing in and breathing out , of the heart pumping blood out and receiving blood in , of all the cells splitting themselves into two and forming new cells .
The healthy body is the great ballet of the billion body parts and parts within those parts ,all doing their ritual rythmic dance in perfect harmony .
What we call cancer , is a let up in the rythmic motions of any part /parts of our body .
If we watch out -or in -periodically we can see who is going out of step to spoil the ballet . We can restore harmony ie health . If we discover it late the ballet may not be restored.
