The Keys to successful developing of intuition and psychic abilities are basically breathe, relax, pretend and imagine, feedback, and practice, practice, practice.
Breathing, relaxation, imagination and practice are Intuition Tools.
Feedback is very important. This helps us learn the language of all aspects of self.
What does seeing a specific object, color, smelling a certain scent, a feeling in a certain part of the body mean to us?
What do these mean in relation to other people?
The way to learn this is to note the occurrence and get feedback from others involved as to what is going on at the time.
