Then comes mastery of the feelings, of the heart. There must be no feeling of revenge, of unkindness, of bitterness against anyone in the heart. When such a feeling comes, one must say: this is rust coming into my heart. When all such feelings are cleared off the heart, it becomes like a mirror. A mirror without rust reflects all that is before it; then everything divine is reflected in the heart, then all inspirations, intuitions, impressions come, and what we call clairvoyance. There is no need to go after such things; they come of themselves.
