When the ego is under control, there is a perfect connection made between the worlds, and the medium is able to accurately convey messages from the other worlds. Those messages are precise, concise and perfect in every way. The medium is at ease with the process, and knows without a shadow of a doubt the information has come from the other other worlds. The medium will feel euphoric and highly positively charged after the connection.
On the other hand, the psychic medium who has 'the chaotic ego' is totally at the mercy of the ego. The connection to the other worlds is limited, with the ego creating alleged connections. There will be a great deal of guesswork and cold reading on the part of the psychic medium, because there is no control of the transmission. The information is sketchy at best, and the psychic medium is left feeling less than euphoric about the whole process.
Sadly there is a large percentage of 'psychic mediums' without the correct basic training. Their control of the ego is limited, and it is completely evident in their arrogant approach to the service they offer. It is a sad situation that really needs to be resolved, and resolved very quickly.
