So, in this Human birth only a chance of attaining relief from the 84 lakh cycle through which the discriminating power which the God or Supreme has given only in the Human Birth. Literally speaking we can see daily that we Human only walk or run on the road by watching the unwanted things on the road but other than human do not do so, It is simple example but made us to understand the discriminating power dealt in us.
