Mechanism of mantr

Now we will discuss how a mantra works on the body and mind.
The modern Mind-Body medicine has conclusively proved that mind works on the body
directly, either in the adverse way or in a beneficial way.
Mind thinks in two ways. One is linear thinking and another is associative thinking. IQ
is associated with linear thinking and EQ is associated with associative thinking. Japa
breaks  both these circuits and allows the  mind to  be in  state of  rest and awareness.  It
gives the mind wakeful rest. This is more effective than a long rest in relaxing the entire
system. When japa of a mantra is done the next thought is known which is not possible
otherwise. This leads to a certainty  of the  mind leading to  rest and  focus.  It  does  not
lead to  monotony as it is stated generally, because each chant is  full  and complete in
itself in meaning and feeling. When a mantra is chanted either verbally or mentally then
it  vibrates  the  brain  matter  and  connects  new  neural  circuits.  This  helps  in higher
understanding  of  the  Truth  as  revealed by  that  mantra.  But this  effect  comes  after
repeating the mantra for a long period of time and bringing in the resonance effect in the
brain.  For  this  the  seers  developed  various  methods.  How  much  a  mantra  is  to  be
chanted and how it is to be chanted etc. were all given in the Mantra Shastra (Scripture
of Mantras)
