On first consideration, a telephone psychic reading may seem to be a very impersonal and remote form of communication. The fact the psychic is doing your reading using a modern piece of technology, possibly hundreds of miles away, may seem at odds with the idea that a psychic is picking up your energies. Surely, a psychic needs some kind of physical proximity, touch or physical connection with the person they are reading for?
In short, the answer is no. When you think about it, the whole conception of being psychic transcends physicality. If I can only do a reading about someone who is next to me, then how could a psychic tell that same person about their partner, family, friends etc. Surely, the rules of proximity would have to apply to them also.
In reality a psychic connection transcends space and time. It comes down to the telephone psychic's ability and intention to interact and help their client. When I do readings over the phone, using tarot cards for example, I will ask the client to focus their mind on the question they wish to ask while I am shuffling the cards. In this context, an open channel is created.
In the case of a clairvoyant reading I may find a particular name or place that a client mentions immediately brings up images and feelings about the client's situation.
In many ways I find a telephone psychic reading forces you to use your psychic ability more deeply. You don't know what a client looks like, you can not read any non-verbal messages. A telephone psychic starts from a truly blank slate, with very few pre-conceptions or judgements.
One word of warning
The only area that can be an issue with telephone psychic readings is the greater possibility of charlatans and frauds. This is no different than any other service on the internet. There are many scammers who will exploit even vulnerable people to get money.
The best way to protect yourself is to make sure the person claiming to be psychic has a well established reputation, either as a psychic line or as an individual. Make sure you can see they have a physical address on their website with phone number. And be clear before you start a reading what they are promising to offer you. If they promise you the world e.g. I will make your lover come back, predict your lotto number etc then run the other way. In particular be careful of telephone psychics offering love spells. I have talked to many clients who have been burnt and lost lots of money through these kind of false promises.
On a more positive note however, in my experience the vast majority of telephone psychics tend to be honest and caring people, who simply want to use their skills in a way that connect to a broader and more diverse group of clients. The best approach is to keep an open but enquiring mind.
