Although inner development is very important for a psychic, without psychic training the progress stands still at a cocoon stage.
Psychic training is basically the testing stage for a psychic. After an inner breakthrough or accomplishment has been achieved, it is time to integrate it, realize it, and put it to use in relation to the outer world as well.
Psychic training is the time to let down the defenses and feel the waves, so to speak. This act, this process reveals flaws or imbalances within the psychic, and also points out the way how to proceed.
Psychic training is not complex - what it requires is courage.
Look for fears on the emotional level, inconsistent thoughts on the mental level, and exclusiveness on the spiritual level. Finding the courage to notice, face, overcome and change these form the essence of psychic training.
