Too bad that people like you waste their hard earned dough and a few days of your lives in dust, poverty and uncleanliness to acccomplish just one object ...trash everything about India: its poverty, people, grass and even its richness..lol.Sadly people like you are so deeply entrenched in the material filth of your lives that you're unable to see and appreciate what India has to offer to the entire world. That inspite of your going to places like rishikesh and attending the yoga camps. But to be honest, your takeaway from it was nil and that is the saddest part. Yoga is not a set of fancy breathing exercises which impacts your physical and mental well being and which you can show off to your brethren in whatever country you come from. It is one of the tools to realize your spiritual existence, yes one of the most bandied words around. But understanding the philosophy of the age old vedic literature requires one's elevation to a transcendental plane of conciousness and elevation to that plane requires freeing oneself from the material energy. Yoga or meditation is one of the tools prescribed by our ancient wisdom to do just that. One cannot expect people like you (who cannot even exhibit the graciousness of a guest or would even struggle to multiply a 2 digit number with another 2 digit number) to reach those levels of conciousness but what is surprising is when presented with an opportunity to do so by the more learned people of India, still came back whinning about the heat and the dust.
Probably this is what god intended for you but the saddest part is that your reviews will end up misguiding the minds of those who were sincere in exploring the world of mysticism beyond the usual pursual of better standards of material living, sleeping,mating and defending which has been likened to a level of conciousness equal to that of an animal existence by our sacred texts.
