Imagine you are going to a public examination ; then some one sneezes ., you think it is a bad omen . You wait for a few minutes & start again . But this time a widow crosses your way . Finally when you fail , whom do you blame ? It is a superstition if you blame her . But if you do not want to blame her , you will agree that coming events cast their shadows . But the question is why should you try to put the blame on her ?It is your brain conditioned by the age old beliefs , that has played the trick .
Man makes certain emperical laws . There is no way for him to test the truth or falsehood systematically , nor can he offer a convincing explanation yet , he holds on dearly to what he deduces . As long as he does not take refuge under the laws he has made , it is not bad . But the moment he absolves himselfn of the responsibility he should bear , they become blind superstitions & unhealthy hindrances on the path of his progress.
The hooting of an owl , the willing of a dog , the cawing of a crow & many such things are superstitions . They are harmless as long as you accept that they are trying to warn you about the coming events . But praying to god with an offer of coconuts for your success in the examination is certainly a very bad superstition . You think you have entered into an agreement with god & he would handover a success card to you ! But satan is also in the race . He will always be there to accept the blame for your sins & failures .
