India has so much to offer to World. Only thing is: We do not patent.
It's our soft power!
India or Hindustan is a platform, open to all, absorbs all good, forces nothing of its own, abstraction is our natural outcome.
Hindu(sthan) is way of life. Its protocol of Life. But open source. No string attached. Nothing proprietary.
And only platforms can be scaled infinite. Rest has by design their own limitations.
