He has given us the map of the Interstate. It is our choice to follow that Interstate or explore other routes along the way. Through personal experience and communications, I have found that my father has reconnected with his I-There, yet continues to appear on occasion as an energy form at the Park. It is easiest for him to appear as a face or as a tear drop form to those still in the physical. The longer one is not in the physical, the harder it is to project a physical-type form.
Communication occurs in many different ways.
It can be visual, auditory, kinesthetic, or through a sense of knowing. It varies with each individual. It was made clear by my father that he would not channel through any physical human being. If he were to communicate through physical means, it would most likely be through a computer or some other electronic means. This is evident through his writing in Journeys out of the Body.
