Meditation is the beginning. It is when we meditate that we are able to fully integrate with our guide. If you feel your face changing then this is the manner in which your will be aware of your connection with your guide.
Each person has a trigger which allows them to know when they are connected. For Joey it is when he perceives us on a point of his head.
So you will see that you will develop this with persistence and by listening for the thoughts which seem to come from elsewhere and indeed do come from outside or you.
