The knowledge brought faith, the knowledge changed, and then faith changed. The knowledge and faith of science is of "happening." In spirituality, faith is first and Knowledge comes later. Like Kriya, Yoga, and meditation -- first you have faith and then Knowledge follows. For example, if you do pranayama faithfully then you get the Knowledge of the prana; if your do your meditation faithfully, the Knowledge of consciousness follows. Even an illiterate, through faith, attains deep Knowledge.
