In science you have knowledge first, and then faith follows.
In spirituality, faith comes first, and then Knowledge follows.
For example, the knowledge that pesticides and chemical fertilizers are good for plants came through science, and people had faith in it, and all over the world they were used. But then knowledge came that they were not good and the faith shifted to organic farming. The same with antibiotics.
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.
Vinod: Human is the best composite material. (Laughter -- this is the NASA scientist mind)
Sri Sri Ravi Shankar: Science considers even human as matter, and spirituality considers even earth as mother, even rivers and mountains as living beings.
Science regards life as matter and spirituality regards even matter as life.
