Hiyas,
I won't move this question because it will be interesting to see the responses it gets here in the psychic forum and if wished we can move it later or re-ask in tarot?
Interesting question. I will answer first from a tarot point of view...... There are many ways of reading the tarot. Some learn the meanings by rote, memorising each card and then when that card comes up they say their speech. Boring but effective most of the time. Others learn intuitive tarot reading like the tarot course I teach here

This bonds what you see and feel from a card to the meaning as defined by your knowledge and experiences, and so can bring up individual meanings that might fit better. Then we can drift onto psychic tarot reading, where the psychic sub-conscious of the reader takes over and adds what they see and feel, and last but by no means least we have the spiritual tarot reader that uses their spirit guide(s) to pass on the messages. Sometimes 'spirit guides' help unknowingly whatever kind of reading you are giving, but they are not necessary for a tarot reading or for that fact any kind of 'tool' reading angel cards or animal cards etc.
You might be interested in the later lessons in the learn tarot course which really help to advance your connection with the cards.
But it all boils down to one thing .... really... anyone can pick up a set of cards and give a reading but will it be any good? That all depends on the reader!
