Can i do Mild Bhastrika for indigestion?

My recommendation has been that self-learners better restrict themselves to Asana only. Even learning asanas by self is not highly recommendable. There is nothing called mild-bhastrika first of all. The sole tone of this pranayama is not ‘gentle’ it ought to be vigorous, deep and even jerky to be accurate. So if you plan to do mild-bhastrika.. it would not be bhastrika at all instead a session of gently fast paced deep breathing.
