Mahamahopadhyaya Yogacharya Dr Ashoke Kumar Chatterjee , author of this book was born in 1933 in West Bengal. The sudden demise of his mother when he was away in service intensely agonized him. He grew averse to material pursuits and became spiritually inclined. He received initiation in Kriyayoga in April 1961. He reached the pinnacle of Kriyayoga within a short span.

His three Gurus were stalwarts in the Kriyayoga discipline.  His first Guru was Sri Annada Charan Shastri (Bhattacharya) disciple of Panchanan Bhattacharya, an elevated disciple of Yogiraj Sri Shama Churn Lahiree. After Sastriji’s demise, Dr Chatterjee obtained initiation from Sundarlal Lalaji of Varanasi, disciple of  Harinarayan  Paladhi,  who  was  the  disciple  of Yogiraj and  later  from  Sri Satyacharan Lahiri, grandson of Yogiraj.
