No one asks you to be like some extremely sensitive mediums who scream at a sick person's bedside because they feel his sufferings. No, but you must learn to put yourself in the place of other people. If you get into this habit, in a very short while, you will become really clear-sighted, intuitive and even clairvoyant. Of course, the majority of people prefer to develop clairvoyance by making use of crystal balls or absorbing certain drugs. Well, this is not recommended. It is better to leave crystal balls and drugs alone and learn to enter into other people's situation. Believe me, that is true clairvoyance, and it is highly superior to that which is practiced by a lot of people who claim to be clairvoyant. The best way to see and feel the essential is to forget yourself a little and think about others.
