Every religious Mohammedan wherever he prays, must imagine that he is standing before the Kaaba. When he makes a pilgrimage there, he must kiss the black stone in the wall of the shrine. Then there is the well of Zimzim. Mohammedans believe that whoever draws a little water out of that well will have his sins pardoned, and he will, after the day of resurrection, have a fresh body, and live for ever. In others, we find that the symbology comes in the form of buildings.
Protestants hold that churches are more sacred than other places.
The church, as it is, stands for a symbol. Or there is the Book. The idea of the book to them. is much holier than any other symbol. It is part of the continuing study of the thoughts, feelings and writings of Swami Vivekananda. There is no reason why man should not use symbols.
