The custom of the seclusion of the mystics remains only in the mystical Orders, but one finds the seclusion of women prevalent in the East. When a custom takes root in a section of society certainly it can be used and abused as people may choose. No doubt jealousy, which is in human nature, is a proof of love, but jealousy can be the source of a great many crimes. Man has always guarded the treasures that he values most in all sorts of coverings, and since that which man can love most is woman he has often ignorantly tried to guard her in the same way as all things of value and importance. And the custom of seclusion has been in his hand a means that has enabled him to control his household in the manner he likes.
