Please, please don't do it. You don't know what you're getting into.
I come from a family with a psychic tradition. Both ancestors and present were involved in diverse activities tarots reading, pendolum, reiki, coffee grounds and others I won't mention.
If anybody thinks that playing with the tarots or any other is just an innocent and harmless game they should start pondering on where the powers to foretell, "heal", affect people's lives etc. really come from. These powers are real.
We're still trying to break the bondage, negative influences and suffering, including ill health, that occult activities invariably bring over those who engage but also their families.
All of our former friends who were also involved in the occult have been in pretty uncomfortable situations and unfortunately, despite the consequences, not everybody succeeds in breaking away.
