Those who desire liberation and eternal happiness need only to comprehend their own system of philosophy. What benefit will they get from criticizing other ideas that are not in concordance with their own system? Still, other ideas that are completely wrong and almost crazy must be criticized to help the dull-witted who might develop faith in them as they are generally accepted and also commented upon with logic and reason. Just as, if a person gives up eating healthy food and instead starts consuming useless junk food, his well-wisher would persuade him to abandon it by warning him about its harmful effects and advise him to resume his healthy diet. Similarly, to safeguard the seekers of truth from anti-Vedic conclusions and inspire them to keep on pursuing truth, criticism and refutation of crazy ideas is must. The book Crazy Ideas logically and systematically refute the prevalent crazy ideas to bring peace and sanity to our confused and chaotic world.
