Our body is the shelter [temple] of our process of life happening in it.The life is the fire of food being oxidised through breathing.Regulation of this fire is the science of spirituality to normalise the process of life at calmness and peace of mind.The mind is the function of our brain and nervous system run by the energy produced by the fire of life.More this fire energy [heat], more the mind is disturbed.Calmness and peace is available with the reduction of this life fire [heat] energy.
