There is no religion in the world where there is a possibility of spiritual development outside of the context of that religion. This is only a modern invention.

Seyyed Hossein NasrIn the field of medicine, if you're sick you need a doctor. A doctor has already studied how to deal with your ailments, and human beings are imperfect.
