The Sunrays series has been created by the perspiration and devotion of Priya & Sanjay Tandon and inspiration from Bhagwan Sri Sathya Baba. it aims at the transformation of the human heart and the gratification of the reader.
The biggest achievement or a book writer would perhaps be the number of copies sold. As far as the sunrays series of nooks is concerned. success seems to be measured by the number of people who have been inspired to better themselves.
