The position that Tarot is evil, I think, dates back to some of the more narrow minded Christian perceptions. A wonderful, warmhearted and friendly lady of my aquaintance cut the friendship dead when she found I study the Mysteries .. and forbade her children to associate with mine. She is deeply involved in a community church and was appalled that I should be heading for absolute damnation for following the heart God gave me.
With others, I have agreed that the Tarot cannot predict the future or have any special powers at all. And I believe that is true. However, as a focus for one's own inner powers of perception, a key to unlock to vision of the soul, a way of bypassing conscious thought and accessing the inner levels of the psyche the whole question can be addressed at a different level.
Those who believe in the immortal soul may well accept that it can see further than we, and that linear time may be a construct of Man and not bind the soul within its constraints.
But unfortunately, there are many who are closed or even violently opposed, by fear, lack of knowledge, or upbringing, to any idea which takes them out of their comfort zone and challenges their perception of the way the world works.
