empathy is the main key. its one word and its fully loaded with all the info you need concerning the keys that matter. it is a tool for awareness and is the only tool we are born with. its the invisible link between all things, and the key to awakening your latent psychic powers. it is also the one common link between all the doctrines of all religions in their teachings, i.e.-all religions teach empathy, the stories vary, but the meanings remain the same. that is all i have to say for now.
