If you want to get famous and have followers in the present world you will have to create controversies. There are umpteen examples of people who have got celebrity status just because of controversies in their life. Before talking about Baba Ramdev I would like to give examples like Rakhi Sawant, Veena Malik, Rahul Mahajan, Dolly Bindra who have made to the top with the help of the controversies in their life.
There are many people who will doubt if aforementioned people are really at the top of their profession. But you will have to accept the fact that despite of limited talent they are standing ahead of many talented people. Somehow they have been helped by the controversies in their life. Even the controversies in the life of these people seemed to be well planned and most of them are created in such a way that news channels relish in covering their life events.
Similarly, Ramdev Baba is also habituated of creating controversies. There are well established and extremely knowledgeable Yoga teachers who are against the Yoga Camps of Ramdev in which thousands of disciples sit under one roof and try to learn Pranayama and other meditation related exercises.
