sanatan
Sanatan Dharma is the purest form of hinduism and hindutva or even every people on earth.Sanatan is what related to adhyatm.Adhya means shakti which again means power and atma means soul so basically sanatan means the inner power which you can initiate by the only thing meditation.It is the way of living,the culture,the father of science.The most of the science is described in sanatan. However the bhagvad geeta gyan of krishna is adhyatma,the mahabharata is hinduism and the yuddh(war) is hindutva.
