Invocation
On another recent thread here on AT, a number of people have been rapidly filling out the mythology of Taroke', a sort of goddess figure who personifies the underlying spirit of tarot,...if I have it right. They have a lot of ideas already for shrines, special days, and so on. So that is one more possibility.
My own personal invocation before every tarot reading is addressed to Hagia Sophia (Holy Wisdom), sometimes described as the feminine persona within God; this is for me and my illumination, and not for the cards themselves, which are after all just lovely printed images on cardboard. The invocation often takes the form of a sort of litany, such as below.
Holy Wisdom, enlighten me.
Holy Wisdom, guide me.
Holy Wisdom, surround me.
Holy Wisdom, infuse me.
Holy Wisdom, protect me.
Holy Wisdom, teach me.
Holy Wisdom, illumine me.
Holy Wisdom, bless me.
Holy Wisdom, quieten me.
Holy Wisdom, speak to me.
etc. with various additions as seem appropriate.
I find it very useful.
What is important is that a person explore approaches that arise from and make sense within the context of their own particular spirituality and worldview.
