Mother is a divine power to all. When the child is unhealthy, she makes the child to drink caster oil and treat the health of child. At that time mother will be bad to the child. So child also will become bad by blaming her mother. But both are good. Like wise good people will cleanse their sins at every point of time and the soul will become pure. The unknown heavens are full of purified souls only. So the pious people suffer to clear off their sins.
The people who commit sins, will be more attracted towards the materialistic benefits, enjoy luxurious lives and so on. They have to forget their sins and do more mischievous acts. The God gave us the brain and thinking power to think what we are doing and be in right path. He has given the human being certain discretion powers and test how far we are using. He can not keep the blame upon him. The people who are in wrong path, do more nefarious acts will not use their discretion, and feel that they are very lucky to enough to have the benefits and crave for them. The cause is Karma (deeds) and effect is again to suffer until the brain gets matured.
