The place where the weight of an object settles is at its lowest point. That is to say, the state where the weight of the body is at its lowest point is called ‘calmness.’
The moon and birds are reflected in the water when the waves on the surface have calmed down. Similarly, the state of mind that clearly reflects existence is called ‘calmness.’
It is natural that humans are calm in their original state. Realise this principle and surely gain true calmness.
