In science you have knowledge first, then faith follows. In spirituality, faith comes first, then knowledge follows. For example, the knowledge of pesticides and chemical plant fertilizers came through science, and people had faith in them; all over the world they have been used. Then another knowledge came that these were not good and the faith shifted to organic farming. The same with antibiotics.
A particular knowledge brought faith, yet when the knowledge changed, then the faith also changed. The knowledge and faith of science is from an isolated “happening” instead of from a fully blossomed Knowledge of life.
In spirituality, faith is first and Knowledge comes later. Like Sudarshan Kriya, pranayama, yoga asanas and meditation - first you have faith and then Knowledge follows. For example, if you do pranayama faithfully, then you get the Knowledge of prana; if you do your meditation faithfully, the Knowledge of consciousness follows. Even an illiterate person, through faith, attains deep Knowledge. Science considers even human beings as matter; spirituality considers even earth as mother, even rivers and mountains as living beings. Science regards life as matter,
Spirituality regards even matter as life.
