Well it is true that traditional indian values, sciences, mythology and knowledge should be kept alive. But the other side of the argument is that people always follow the those who are successful. In the present time, the western ideology, thinking, science and knowledge has proven to be useful, correct and commonly available to everyone in the world. We live in a global village, and everyone has access to everything.. it can be difficult for a person suffering pain, to get treatment from ayurveda or prayanama and completely ignore allopathic medicine.. all he wants is fast pain relief. similar argument applies to the rest.
how can a person believe in a saadhu, whose past and present are dubious, and who may even be a criminal out to dupe you?
Most of all, an uneducated and unemployed person will go to any extent, even to conversion, to get 2 square meals for his family as religion is the last thing on his famished mind..
