Very often people divide the esoteric or inner part of life from the exoteric or outer form of religion. But although to divide them in a conception is possible, to divide them in reality is like separating the head from the body. As the head linked with the body makes the form complete, so religion together with inner life makes the spiritual ideal perfect. Nevertheless, the thoughtful and wise of all ages, with their philosophical minds, with their scientific tendencies, with their intellectual strife, often thought of separating religion from the inner life. But when they are separated, it is just like bread without butter, it is like milk without sugar, it is like food without salt.
