I actually find it easier to connect remotely than face to face. perhaps Im distracted face to face.
To start I take myself down a few notches, relax and focus of them. that my clients have come to be I take it as permission, other readers I know ask their clients to relax, direct the bathing of white light over them and tell their guardians that they are asking for communication through them. For me it was a conscious choice for the client to choose me and I dont start reading until the clients says they are ready, I take that as permission.
Il then draw one card to see if it relates to the client. I work with angel, or spirit guidance so I ask that they show me the client, the card I draw should then relate very much to that client. If not I dont continue reading.. If it doesnt relate IMO I have not got a clear connection and from experience its not going to happen so I explain to them that I am faulty. I need to be careful then so that the client understands that their guardians are with them, Im just not getting it. My greatest fear is that my poor client would be feeling alone because I missed the connection.
Its important not to ask questions apart from what helps you get the connection between the client. asking to many questions takes them "wow" moments away, and I like them.. Also keep in mind that message may not make sense to you, its the client that it has to make sense to.. whats going on is none of my business.
If the reading is truly sounding messy Ill stop and ask if there is any sense to what they have so far.. There are times we get side tracked, be honest with the client when that happens.
having the client tell you what they want to focus a reading on is also important unless you have all day, and typical they have a question they want answered. fail to answer that question and get a bad review.
be honest with the client up front. explain to them your service and what you can and cant do. I dont usually predict eg.. I am diligent in explaining this to a new client..( some still dont get it, and will push for predictions ).. sometimes I get predictions sometimes I dont. I tell clients "I can be wrong" often when I am trying to find a prediction for them.
%100 right is a tall order, if you claim that be that.
One of the worst things you can do to a client is give them false hope, the next worst thing you can do is leave them with no hope at all.
Very typical scenario:
Client comes after a breakup with their boyfriend, wants to know if they'll get back together.
me: Im sorry I cannot answer that question, ( explain my way of working again, because they dont read profiles) I can offer you a reading to help you deal with this difficult time.. or something or rather..I dont have a copy and paste line

)
*click*.. but if they stay.. yea..
If I do feel the reading is offering a clue that the chances of a reunion are not likely, I will tell them this is what it is feeling like to be BUT.. the end of a relationship is the closing of one door so that you will walk through the new open door.. There is a positive to a relationship ending and I take the time explaining new beginnings and the importance to moving on.
I will not leave a reading on a negative.. not ever ever. I dont care if I have to use an hour of unpaid time Its my mission to empower them. If I cant do that I failed by accepting a client that was beyond my ability. this is my responsibility to my client.
You should never read on health issue, and never read for someone that is suicidal or clinical depressed, gauge a clients state of mind.. if it is unstable, you should not read for them.
Have a handy list of professional help lines they should call.. in particular suicide prevention.
I say this for your protection as much as the clients. An unstable or suicidal client is like an energy vampire, You'll end up an emotional wreck.
I hope this has helped some..
Im sure tarot readers will come along and be more specific to your preference and style.
