Science is uncomfortable with anything it cannot see, feel or observe. So ‘spirit’ is out of bounds for science. It is not only recently that mind/ brain study became acceptable as neuroscience.
At a broader velvet, there is no conflict between science and spirituality — both aim at human betterment. The conflict is only between scientists and spiritualists.
However, science is not concerned with ethics. Science can be used for good or bad purposes. Spirituality looks at the underlying unity of all organisms.It seeks to resolve conflicts. Science has no grand purpose to deliver humanity from hatred and mutual destruction.
It is very difficult for science and spirituality to speak in a common language. They only can seek to find common ground.
