It is not advisable to bear pain,to torture ourselves/our body ,by beating ,by walking bare foot,by fasting too much or by any other means-in the name of religion.
However, if we bear pain for happiness of others ,to grant relief from pain,by serving for somebody during sickness ,by helping poor persons to fulfill their bare minimum requirement,by teaching somebody if we are scholar or by any other means then certainly, it shall be much more fruitful for us,in the name of the God.
