Namaste, I think Karapatri-ji refuted this work and wrote a book to counter this. Reading such books doesn't serve our purpose of search for Truth & Eternal Happiness. Arya Samajists are iconoclasts and doesn't believe in Ramayana, Mahabharata & Puranas. Their's is 'anglicised veda'. Better to stay away from such notions. rg, sriram
