Dear @ShivaPrakkash,
I completely agree with the suggestion given by Rakhi ji. Why should we take steps in pitch dark where we could be at the edge of the hill. I would also suggest, not to try something which is not known well to us.
Have you seen a fruit seller who say that – Please don’t buy my apples as they are not sweet" ?
You must have observed that all Orange seller claim that his Oranges are from Nagpur. So, when a fruit /vegetable seller will brag for his product then this is an Elite area. All will declare their technique to be the best. But we shouldn’t be a blind follower. That is why we have a book of testimonials for all VK aspirants which has various successful experiences of different people like me and you.
Now, Black magicians also bring out great & instant results, but it is our decision whether to follow or not.
VK has the power to mimick any healing technique on the earth but provided that it is a positive one. As I tried to find out about Thamba it connects to African technique of some dangerous practices for which a healer needs to have permission.
Moreover, my way is like Karate / Kung-fu style. If I am following Shotokan style then I will try to become a Master at it instead of keep on searching for all the other styles and become a Jack of them.
