It was pleasure to watch this film. I applaud the makers of this film for bringing out this wealth of knowledge; making people aware of this ancient science. Such simple film-making and yet so impacting.
It is worthwhile to note that many secrets of Ayurveda and Siddha Yoga are a part of traditional family wealth, hence there are not as many practitioners with the profound knowledge as the Swami in the film.
Calling these practitioners as quack or charlatans is like being steeped in ignorance from this ancient art of living. Make a thorough study of how well aware the ancient people were about the body and its mechanisms at the deepest levels...unless that is done, well... everybody has the right to be ignorant and bound in their concepts and post comments as they wish. !! One should understand these true Ayurvedic doctors (in the film) are those who come from a spiritual foundation and hence their knowledge and practice is based on service to humanity and not building mansions out of the returns (which itself is based on donations in most cases). Real masters of Ayurveda are rare and the ignorance of many about it is abundant (especially those feeling their flavor of science is the only right one) but that does not make this beautiful science any less. In fact it is most open to modern medicine (which is precisely noted in the film). CT scan, PET, MRI are wonderful tools in modern medicine as well as its great surgical techniques. Ayurveda is open to blend these with its innate repository of the most profound knowledge of the human levels of existence (which includes the body). Would anyone say modern medicine is as open to embrace any dimension of Ayurveda !?
Remember, Ayurveda is not just medicine ..it is the art of healthy existence... it needs good marketing...for what ?? for the benefit of humanity !
