Aura and Energy Circle Increase by Yoga and Prayer

just read a pocket book on an offbeat topic of individual aura and energy circle increase.

Gist of the whole 100 page book is:

Increase your personal aura and energy circle by:
1. Prayer
2. Pranayama Yoga (bramari, anulom vilom, kapal bhati, Bhastrika, udgeeth, Bahya)

I found the above to be certanly beneficial, but how useful in they increasing the energy circle.....i keep ths issue open.
