The preface mentions 'our land of Aryavarta'. What does the author define this region as?

The preface does not provide a geographical or historical definition for the term 'Aryavarta'. Within the context of Chapter 0, the author uses the term simply to denote the land where a specific belief system is firmly established. This core belief, described as ancient and supported by Vedic scriptures, is that "there is no salvation without the grace of a Sadguru." The focus is on this spiritual principle and its deep-rootedness in the culture, rather than on defining the physical or political boundaries of the land itself.
