Sitting near the fire warms and protects us even in harsh winter.  Fire spreads the heat in the surrounding area.  That way, our body also has heat in it.  The clothes we wear also become warm by the heat of the body.  This effect is more noticeable in winter by touching the clothes that we are going to wear.  Wearing woollen clothes in winter protects the emission of body's heat outside and thus helps keeping the body at natural temperature.  The body-system also possesses many other kinds of energies in it.  But most prominent intense and radiant of the powers a human being is endowed with is thought-power.  (Akhand Jyoti English March-April 2011)
