Although the cards were inspired by the Tarot, Raman says that unlike the Tarot, no expert is needed to interpret them. The only expertise is with the process. This is very new for most people. There are no winners or losers. Raman says we have a peculiar relationship with chance in this culture.
Chance scares many people.
We can use the cards to tap into our subconscious to discover truths or secrets about ourselves. While people do not need any advance preparation before using the cards, Raman does suggest that people bring an attitude of curiosity, willingness and serendipity, in an experiential rather than technical sense. He says some people choose to centre themselves through meditation beforehand. People are free to customise their OH experience to suit their needs but to gain the most from the cards, he recommends people first read the guidelines enclosed with each deck. There are no incorrect interpretations, only different perspectives.
