At the World Yoga Convention held in 2013 on the occasion of the Golden jubilee of the Bihar School of Yoga, Swami Niranjanananda announced:

"The First chapter of yoga propagation is over. Now the second chapter begins, which is focused on consolidation of yoga and better application of yoga, with sincerity, seriousness and commitment."
In writing the second chapter, a complete change in the training programs at Ganga Darshan Vishwa Yogapeeth has come about since 2016. The new programs are setting a standard of understanding

the practices and principles of yoga from the perspective of the original is intentions of yoga.
Among these programs was Kriya Yoga — Preparatory, during which the focus was on understanding and practising the first group of kriyas, the pratyahara kriyas.
This book presents the satsangs given by Swami  Niranjanananda during the program, during which a new insight into pratyahara and its association with this group of practices was revealed.
